Abstract:
In this paper, the authors have proposed a new prediction-based location management scheme for cellular networks. The current mobile switching centre predicts the previous mobile switching center of user, and then imports the data about the mobile terminal from that. For this purpose it uses a prediction table, which is based on the neighboring location areas. The analytical model and formulation presents the conceptual schema of proposed scheme. The performance comparisons and numerical analysis is helpful to find out the efficiency and effectiveness of the proposed system, with respect to existing location management techniques. It has been observed that, the registration cost, and the network overhead at mobile switching center have been reduced in the proposed prediction-based scheme.

Abstract:
<em>The aim of this work is to characterize and develop a model for the determination of the cooling reliability of a mobile switching centre. From the analysis done with the reliability block diagram models (RBD), it was observed that the combined cooling reliability, MTBF and failure rate (&lambda;) is 58.54%, 1389hrs and 0.000719704 respectively. Further checks on the combined cooling reliability gave 83.53% at 250hrs for the same failure rate which calls for urgent and stringent maintenance programs developed for the 250hrs cycle in addition to the already existing 744hrs cycle. This should be proactively applied to the cooling units on a need basis to increase the MTBF and the reliability of the older units to 99.982% required for high performance and public safety as specified by ANSI/TIA, especially during the heat season of the year.</em>

Abstract:
This study is on the analysis and modeling of intelligent channel allocation techniques in mobile communication systems where different channel allocation techniques were considered in mobile communication systems. Also, the different channels which are used in the cellular networks were sufficiently described. Various parameters in mobile communication system that are related to channel allocation techniques and blocked calls were identified and discussed. Data collection was carried out from the Network Switching Center of a highly established and reputable Telecommunication Operator. Data were collected both from the Base Transceiver Stations (BTS), the Base Station Controller (BSC) and the Mobile Switching Centre (MSC), at different locations in Nigeria. These data were collected at different times on monthly basis for a period of thirty six (36) months in the course of this study. Proteus software was used to analyze data collected to enhance the simulation set up. A model (GRACE MODEL) of intelligent channel allocation technique algorithm was developed to reduce the call blocking and also call dropping probability. To authenticate the effectiveness of the proposed algorithm, the simulation result was demonstrated respectively showing normal capacity; over capacity; rerouting to neighbouring sector, e.t.c. It was observed that with the use of the proposed channel re-assignment strategies algorithm, the radio coverage at large distances had more increase in the system channel capacity. It was also observed that the blocked calls (the chance that a call will have no service) were highly reduced due to intelligent philosophy in the developed model. Additionally, the model helped to scale up performance and provided great improvement in network spectral and energy efficiency.

Abstract:
The sliding window algorithm proposed for determining an optimal sliding window does not consider the waiting times of call setup requests of a mobile station in queue at a Mobile Switching Centre (MSC) in the Global System for Mobile (GSM) Communication Network. This study proposes a model integrating the sliding window algorithm with a single server finite queuing model, referred to as integrated model for measurement of realistic throughput of a MSC considering the waiting times of call setup requests. It assumes that a MSC can process one call setup request at a time. It is useful in determining an optimal sliding window size that maximizes the realistic throughput of a MSC. Though the model assumes that a MSC can process one call setup request at a time, its scope can be extended for measuring the realistic throughput of a MSC that can process multiple call setup requests at a time.

Abstract:
This work addresses the development of a distributed switching control strategy to drive the group of mobile robots in both backward and forward motion in a tightly coupled geometric pattern, as a solution for the deadlock situation that arises while navigating the unknown environment. A generalized closed-loop tracking controller considering the leader referenced model is used for the robots to remain in the formation while navigating the environment. A tracking controller using the simple geometric approach and the Instantaneous Centre of Radius (ICR), to drive the robot in the backward motion during deadlock situation is developed and presented. State-Based Modelling is used to model the behaviors/motion states of the proposed approach in MATLAB/STATEFLOW environment. Simulation studies are carried out to test the performance and error dynamics of the proposed approach combining the formation, navigation, and backward motion of the robots in all geometric patterns of formation, and the results are discussed.

Abstract:
Dense deployment of cellular networks is leading to scarcity of communication bandwidth or what we call as channel. If compared to its wired counterparts, wireless cellular network have limited number of channels available, which gives rise to problem of efficient channel allocation. Here, in this piece of work, the main objective is to put an effort to improve existing channel allocation scheme. In earlier existing hybrid allocation scheme, the base station notifies about the hot-spots to the Mobile Switching Centre (MSC) and if MSC has available channels in its central pool then it satisfies the request. Now, the novelty of this work starts where central pool gets exhausted and request of channels from base station (BS) still arrives and is served by returning the unused channels by different cells back to MSC on its request. The simulation of this approach is expounded and evaluated over OMNeT++ in a scenario with fixed channel allocation and hybrid approach by varying the proportion of dynamic channels to total number of channels available and the effectiveness is evaluated in terms of Call blocked and Call dropped versus System load.

Abstract:
The ability of a mobile robot to move in the environment is an important task in robotics, so the development of advanced control systems for robots is a hot topic of research. Clear logic control systems for robotic-wheeled machines are one of the most common. Such systems are simple in design, but still have the lowest cost compared to others. One of the disadvantages of such control systems is their limited accuracy. This is usually due to imperfect control programs on which similar systems work and the imperfection of the mechanical system of drive converters, in particular for wheeled robots with differential drive, there may be cases where the robot with clear logic control can endlessly search for targets and move to a given point in space, even in the absence of obstacles in its path. This study proposes an analysis of the movements of a two-wheeled robot according to the developed algorithm of clear logic. A mathematical model of the step-by-step movement of a wheeled robot was developed, which calculates the coordinates of the centre of the mobile system. The decision-making system in the developed model is built on a relay ("ON-OFF") controller. In this study work, the authors also proposed a method for determining the moment on the rotor of the drive motor of the robot wheel, depending on the speed of the robot on a straight surface. In addition, the dependences of the change in the speed of a wheeled robot with a differential drive depending on the change in the PWM frequency in the range from 30 to 60% have been studied and presented. Graphs were presented that show how the switching frequency of the robot controller changes when it moves to the desired goal of movement in a straight line without obstacles.

Abstract: After drunken driving, mobile phone usage is the leading cause of accidents around the world. Also, at sudden stoppages on cross roads or due to sudden obstructions on road, natural or otherwise the driver cannot anticipate back bumper and side collision. Also, low height railing or pavements in blind spots while parking may damage the vehicle. Costly mobile phone jammers while effective render emergency communication impossible. As alcohol detection and vehicle tracking system are successfully implemented we are proposing an essential vehicle safety kit which is absent in majority of the vehicles on Indian roads. Furthermore, this can be an addition to the developing cognitive driver assistance system. The proposed system provides vehicle with safety features like SMS alert facility, blind spot detection and tail gating detector. The vehicle is equipped with angle sensors and a GSM modem interfaced with NXP ARM 2148 processor. The driver has access to a user interface consisting of LCD and switching ports. The driver may aware two modes of angle sensing with sensors located on centre of the Vehicle. A braking system can be actuated in the parking mode if the distance measured from the sensors crosses the defined threshold. In case of an emergency the driver can send a text or call from the stored numbers in the memory using the keypad. To save time and to maintain the driver’s focus on the road a default text can be sent to a default number by a single key pad entry. Call service from the system eliminates the need of using the phone and prevents driver’s loss of focus. Further the freedom to choose the number and the corresponding message to be sent is available when the vehicle is at rest. The system thus prevents accidental damage to the vehicle and its driver while eliminating the use of phone by the driver.

Abstract:
&lt;span&gt;This paper aims to save thousands of lives by proposing a novel technique of ensuring the complete safety of medium-sized aquatic vehicles using innovative ideas as well as augmented adaptations of myriad existing technologies. The proposed system incorporates a warning and danger level detection circuit using transistors for switching purposes when the vehicles are overloaded, and a Global System for Mobile (GSM) based module so that the control room can receive alerts and control the engines of such vehicles centrally. A system for detecting and avoiding obstacles is made using ultrasonic radar with ultrasonic transducer JSN SR04t mounted on top of SG90 servo arm which rotates to detect any obstacles. When an obstacle is detected, two other ultrasonic sensors SR-04 gets activated which are placed on two sides of the aquatic vehicle and the ultrasonic transducer becomes fixed on the exact centre. All the three sensors work together to find a free path for the boat to travel. If there is no free path, the boat will stop and wait for the paths to get cleared. The location of the vehicle is tracked by the Global Positioning System (GPS) and a Proportional-Integral-Derivative (PID) controller has been included along with a system which uses values from the GPS module to come back to its original path if it deviates from the original path when avoiding obstacles. A barcode system has been added where it keeps a count on the passengers. The tickets for the vehicle will have barcodes on them which will let the passengers in only if the barcode matches. This is used mainly to keep track of how many people are boarding the vehicle and to prevent those without tickets from boarding.&lt;/span&gt;

Abstract:
<em>The aim of this research work is to develop an adaptive controller to mitigate the impact of cooling failure in a mobile switching center prefab room(s) during power or cooling failure. Heat build-up inside the telecom room is unavoidable since the cooling systems do not work during a power outage causing rapid rising temperature above ASHREA recommended guideline of 18 to 22oC for optimum performance. This heat if unmanaged during a power loss leads to total or partial services downtime, and as a result, data is lost, customer quality of experience (QoE) is impacted, business reputation is damaged, and revenue is lost. The characterization and simulation results presented in Table 2 and 5 shows that the combined cooling reliability of all the prefab rooms was 58.54% at 744hrs and suggests that only 58.54% of the prefab rooms can sustain cooling after a one-month cycle period. Further checks on the combined cooling reliability gave 83.53% at 250hrs for same failure rate and calls for urgent and stringent maintenance program to be developed for 250hrs cycle and proactively applied to the cooling units on a need basis to improve the reliability of the older units especially during the heat season of the year. This should be in addition to the already existing 744hrs maintenance cycle. Also, the test result of the developed Adaptive controller shows an improvement in MTTR from about 60 mins to &lt; 2 mins and validates the ability of the controller to improve the overall system reliability to 99.982% required for high performance of the switching center and public safety as specified by ANSI/TIA. Lastly, the developed Adaptive controller will mitigate the impact of cooling failure in any of the mobile switching center prefab rooms and can be implemented in any telecommunication room where cooling is critical for optimum operation.</em>

The main algorithms for ensuring the confidentiality and security of mobile subscribers' data, in different types of standards, as well as the vulnerabilities of information flows are considered. In particular, the following dangerous types of attacks have been identified, to which mobile network subscribers are sensitive: sniffing; leakage of personal data; leakage of geolocation data; spoofing; remote capture of SIM-card, execution of arbitrary code (RCE); denial of service (DoS). It is established that the necessary function of the mobile network is the identification of subscribers, which is performed by IMSI, which is recorded in the SIM card of the subscriber and the HLR of the operator. To protect against spoofing, the network authenticates the subscriber before starting its service. In the case of subscriber identification, the subscriber and the network operator are protected from the effects of fraudulent access. In addition, the user must be protected from eavesdropping. This is achieved by encrypting the data transmitted over the radio interface. Thus, user authentication in UMTS, as well as in the GSM network, is carried out using encryption with a common key using the "hack-response" protocol (the authenticating party sends a random number to the authenticated party, which encrypts it according to a certain algorithm using a common key and returns the result back).

Abstract:
In this research, we propose a novel wheel-legged mobile robot to address the problems of insufficient obstacle-crossing performance and poor motion flexibility of mobile robots in non-structural environments. Firstly, we designed the transformable wheel mechanism and tail adaptive mechanism. Secondly, the kinematic model of the robot is established and solved by analyzing the whole motion and wheel-legged switching motion for the operation requirements under different road conditions. By synthesizing the constraint relationships among the modules and analyzing the robot’s obstacle-crossing abilities, we systematically established the mechanical model of the robot when it encounters obstacles. Thirdly, we studied the stability of the robot based on the stable cone method in the case of slope and unilateral transformation wheel deployment and achieved the tipping condition in the critical state. Finally, we used ADAMS software to simulate and analyze the driving process of the robot in various types of terrain and obstacles in order to verify that it has superior performance through obstacles and motion flexibility. The analysis shows that the robot can passively adapt to various complex and variable obstacle-filled terrains with obstacle heights which are much higher than its center of gravity range. The results of the study can provide a reference for the structural optimization and the obstacle-crossing performance improvement of mobile robots.

Abstract:
Abstract. Compared with the traditional mobile robots, the new concept mobile robots have greater deformation capability and richer mobile gait; similarly, they have a better capability to adapt to the environment. This paper presents a ring four-array rolling mechanism that consists of four anti-parallelogram mechanisms with revolute joints. The mechanism is connected by four anti-parallelograms in a looped configuration and has a not-totally-closed ring shape, whose external contour is similar to that of a quadrangular prism. The mechanism has planar and spherical patterns of locomotion, in which the planar pattern of locomotion includes the parallelogram rolling gait and the anti-parallelogram tumbling gait, and the spherical pattern of locomotion includes the spherical rolling gait. On this basis, the kinematic analysis of the two patterns of locomotion is carried out to obtain the positions of each point and the center of mass (CM) of the mechanism. The feasibility of the rolling locomotion of the mechanism is verified by the moving trajectory of the CM. According to analyzing the feasibility of the mechanism's obstacle-crossing and moving strategy, the mechanism is made to complete the switch between different motion modes. Through the establishment of a dynamic model and simulation, the analysis of the rolling gait of the mechanism is completed, and a prototype is made for experimental research. The results show that the anti-parallelogram ring four-array rolling mechanism has the basic rolling capability of linear movement and steering. Furthermore, in the initial state of the mechanism, the mechanism enables flexible switching between multiple rolling gaits.

Abstract:
Customer loyalty is a phenomenon that is the center of attention of an organization or company because it greatly influences the continuity and development of the organization. Customers are said to be loyal if they have affection for a company's products or services. So that loyal customers will express this affection by saying positive things about the company's products or services to friends, relatives and co-workers. However, if customers feel uncomfortable with a company's products and services, there is a possibility that customers will switch from loyal to disloyal. This is usually called customer switching. This research is based on a systematic review of the influence of usability and ease of use of online shopping applications as well as the factors causing customers to switch from online shopping applications to mobile retail applications. Three phases are used in this study's systematic literature review (SLR). The factors that were discovered were categorized using three main themes. Interconnected among these three elements are perceived utility, perceived ease of use, and behavioral intention to use. This study also found that when TAM is added as a new component to gauge the intention to adopt an online shopping application, "trust, ease, and information quality" are the most important factors. By carefully identifying the effects of online shopping application on business management, this research contributes theory. The findings assist online shopping application service providers in formulating sensible plans for foreseeing and enhancing clients' intentions to use online shopping applications.

Abstract:
Abstract In this work, we propose a sixteen channel wavelength division multiplexed passive optical network (WDM-PON) architecture which provides seamless connectivity between mobile switching center (MSC) and base transceiver stations (BTS) and also serves the fiber to the home (FTTH) users. WDM-PON based mobile backhaul network is considered to be a prime solution due to its quick deployment and reduced cost. Due to growing demand for connectivity and data transmission, the number of wavelengths are increasing day by day. The bit error rate (BER) performance is analyzed for the discrete data rates per wavelength (viz. 2.5 Gbps, 5 Gbps, 10 Gbps, 20 Gbps, and 40 Gbps) at discrete reach for 16 channel WDM-PON. The optical spectrum of sixteen channel WDM-PON is observed for different data rates at multiplexer output and the same is analyzed after fiber distance of 20 km. The fiber reach of the WDM-PON is varied, and its effect on the performance parameter like bit error rate (BER) and Quality Factor (Q-Factor) is observed on BER analyzer for the discrete data rates per wavelength. It is found that as data rate per wavelength increases, the error-free reach of the WDM-PON system decreases. Proposed WDM-PON architecture performs superior to the compared work under similar initial conditions.

Abstract:
Due to the portable property of moveable radiation sources, the traditional monitoring method is becoming increasingly unsuitable and it is urgent to provide an effective and low-cost method. This paper presents an active monitoring scheme for moveable radiation environments, the in situ monitoring, including a radiation detection node, an infrared proximity node, and an alarm node; these three schemes communicate with each other through the ZigBee wireless network. An active monitoring mechanism which realizes the automatic judgment of radiation source inbound or outbound state is proposed, thereby automatically switching the data sampling mode under different working conditions, so as to reduce the energy consumption of nodes. Based on the mobile terminal client application to interact with the monitoring center, a collaborative management mode between enterprise users and the environmental protection department is realized. A testbed of a simple active sensing and inspection system is created to test its user interaction capabilities. Experimental results prove that the system schedule proposed can effectively detect and dynamically monitor the moveable radiation source. The system can be easily replicated and extended to more environmental monitoring network.

Abstract:
This research investigates and analysed generic Wireless Local Area Networks (IEEE 802.11a/b/g) in the context of their Quality of Service (QoS) in high density networks using some generic Key Performance Indicators (KPI) such as throughput (Bytes/Sec), Received Signal Strength Indicator (RSSI), and latency response (secs). The study focused on University of Nigeria Nsukka (UNN) which houses several hostels and faculties. Using Applied Research Methodology (ARM), this work characterized a real life generic hotspot testbed (UNN) for Received Signal Strength (RSS), mobile node distance, latency and throughput using Tranzio-Wavion Minipop Infrastructure in UNN as the network testbed. In this study, after sampling the selected KPIs, data were collected via our testbed measurements from the test nodes, Network Switching system/Network Operating Centres (NOCs) and their values were evaluated for an assessment study. The KPI results obtained showed that the traditional generic WLAN will scarcely scale in high density traffic environment in terms of scalability, speed performance (network convergence), cost, and other selected KPIs. This will lead to a proposal on a conceptual framework for Cognitive High Density Hotspot (CHDN) in our future work, which will address the limitations of generic WLANs for enterprise computing.

Abstract:
A compact flexible multi-frequency antenna for smart portable and flexible devices is presented. The antenna consists of a coplanar waveguide-fed slotted circular patch connected to a rectangular secondary resonator (stub). A thin low-loss substrate is used for flexibility, and a rectangular stub in the feedline is deployed to attain wide operational bandwidth. A rectangular slot is etched in the middle of the circular patch, and a p-i-n diode is placed at its center. The frequency reconfigurability is achieved through switching the diode that distributes the current by changing the antenna’s electrical length. For the ON state, the antenna operates in the UWB region for −10 dB impedance bandwidth from 2.76 to 8.21 GHz. For the OFF state of the diode, the antenna operates at the ISM band (2.45/5.8 GHz), WLAN band (5.2 GHz), and lower X-band (8 GHz) with a minimum gain of 2.49 dBi and a maximum gain of 5.8 dBi at the 8 GHz band. Moreover, the antenna retains its performance in various bending conditions. The proposed antenna is suitable for modern miniaturized wireless electronic devices such as wearables, health monitoring sensors, mobile Internet devices, and laptops that operate at multiple frequency bands.

Abstract:
From the beginning of the XXI century mankind is experiencing the fourth Industrial Revolution Industry 4.0. This process is a massive introduction of cyber-physics systems, systems for processing and analysis of large data arrays, the use of InternetofThings in industry and automation, and widespread digitization [1]. InternetofThings closely connects various types and types of devices, enterprises, technology, mobile communications, etc. [2]. Such an association within the industry poses high requirements for safety, reliability, speed, uninterrupted work and protection of devices, as well as communication channels between them. On its own, high requirements apply when it comes to objects with critical infrastructure. The category of such include nuclear power plants (NPPs). In this article, a model for data transmission to a crisis center in the event of an accident is proposed. Also presented software and technical implementation of the proposed model. This work is devoted to the creation of a prototype of a software and hardware complex simulating the process of monitoring the NPP power unit. Software-hardware complex is a practical implementation of one of the proposed models of systems after emergency monitoring (RAMS). The development consists of two levels. At the lower level, which is the hardware level, there are sensors, microcontroller, hardware. At the upper level is the information system, which allows within the crisis center to get the values of indicators from the sensors in a convenient and visual form, to store, archive data. In addition, the crisis center has the ability to control the system stabilization of the power unit during an accident, for example, by switching on cooling devices. Data from the power unit can be quickly received by external experts (EEs) located in other countries of the world, without losing time to install software applications or specific software. Crisis center and a group of external experts take decisions on the elimination of the accident or through the usual situation. Due to the proposed model of data transmission, it is possible to obtain as much data as possible about the state of the accident for further liquidation. The article also presents the experimental part of the work.

Abstract:
Abstract Background: The telehealth approach offers enhanced service delivery for older patients living in rural areas. Purpose: We conducted a pilot study to evaluate the feasibility of using the Zenbo robot to improve the quality of care of elderly individuals with dementia. Methodology: In this study, we developed a digital solution on service robots and smart devices, which can leverage the capacity of the user-friendly interactive interface and digital dialog system. A group of eleven volunteered older adults was selected for this study. To assess the likability and acceptance of the Zenbo, we conducted a one-on-one (robot vs human) pilot study in our long-term care stations. Each participant engaged in conversational interactions for five consecutive days and completed a survey of 12 questions about the experiences they had with the Zenbo, at the beginning and the end of the study respectively. Results: Subjects with lower GDS-15 scores have more positive attitudes toward the robot before the intervention. 27% of older adults had an increase in positive attitudes toward the interaction with the Zenbo robot. With the aid of teleoperated mobile robotic systems at home, the innovative service model can be achieved through telecommunication between primary health professionals or caregivers at remote locations and psychiatrists at the medical center to make the seamless care environment real. Conclusion: The IoT technologies can be used to assist physicians in switching from a hospital-centered model of care to a home-based service for older people with dementia. It merits more future clinical trials and usability tests.

Abstract:
Abstract. Automation of agricultural machinery is aimed at solving specific practical tasks: control and maintenance of the technological process quality, increasing labor productivity as well as crop yields. The method of "precision farming" is economically expedient, since it is a direct saving of technological material, as well as it helps reducing the negative impact on the environment and farm produce. (Research purpose) The research purpose is to review and analyze the main aspects required to develop the algorithms and software for motion control systems for a robotic tillage unit. (Materials and methods) To implement process control, it is necessary to control the direction of travel along a specified path, change the speed of movement depending on the engine load, switching the transmission gears. Physical-and-mechanical characteristics of the unit are rather heterogeneous and depend on weather conditions. Therefore, the algorithm for controlling the power of the robotic mobile unit must take into account, as much as possible, variations in the external effects of drawbar properties and the motion resistance, as a random factor. (Results and discussion) The authors have developed an imitation model representing the movement of a robotic unit. For the simulation, use has been made of a cyclic trajectory of the unit movement, consisting of two types of sections: the rectilinear ones reflecting the soil tillage pattern, and the turn areas where the unit makes a turn along a curvilinear trajectory around a certain center. (Conclusions) The implementation of robotic technologies in agricultural production result in increased technical, technological, production and economic indicators of agricultural units in field work, increased labor productivity, reduced time required for fieldworks, more rational use of bioenergy resources, increased yields of agricultural crops and reduced environmental impacts.

Abstract:
Purpose This study aims to develop a compact analytical models for undoped symmetric double-gate MOSFET based on carrier approach. Double-Gate (DG) MOSFET is a newly emerging device that can potentially further scale down CMOS technology owing to its excellent control of short channel effects, ideal subthreshold slope and free dopant-associated fluctuation effects. DG MOSFET is of two types: the symmetric DG MOSFET with two gates of identical work functions and asymmetric DG MOSFET with two gates of different work functions. To fully exploit the benefits of DG MOSFETs, the body of DG MOSFETs is usually undoped because the undoped body greatly reduces source and drain junction capacitances, which enhances the switching speed. Highly accurate and compact models, which are at the same time computationally efficient, are required for proper modeling of DG MOSFETs. Design/methodology/approach This paper presents a carrier-based approach to develop a compact analytical model for the channel potential, threshold voltage and drain current of a long channel undoped symmetric DG MOSFETs. The formulation starts from a solution of the 2-D Poisson’s equation in which mobile charge term has been included. The 2-D Poisson’s equation in rectangular coordinate system has been solved by splitting the total potential into long-channel (1-D Poisson’s equation) and short-channel components (remnant 2-D differential equation) in accordance to the device physics. The analytical model of the channel potential has been derived using Boltzmann’s statistics and carrier-based approach. Findings It is shown that the metal gate suppresses the center potential more than the poly gate. The threshold voltage increases with increasing metal work function. The results of the proposed models have been validated against the Technology Computer Aided Design simulation results with close agreement. Originality/value Compact Analytical models for undoped symmetric double gate MOSFETs.

Abstract:
ImportanceWith the prevalence of e-cigarette use (vaping) increasing worldwide, there are concerns about children’s exposure to secondhand vapor.ObjectiveTo compare nicotine absorption among children who are (1) exposed to secondhand tobacco smoke only or (2) exposed to secondhand vapor only with (3) those exposed to neither.Design, Setting, and ParticipantsThe US Continuous National Health and Nutrition Examination Survey (NHANES) is a repeat cross-sectional survey. Participants are interviewed in their homes and, several days after, visit a mobile examination center to provide biological specimens. This study uses data from a nationally representative sample of US households from 2017 to 2020. Participants were children aged 3 to 11 years with serum cotinine levels incompatible with current firsthand nicotine use (ie, &amp;amp;lt;15 μg/L). The final analysis was conducted on January 9, 2024.ExposuresReported exposure to secondhand smoke or vapor indoors in the past 7 days (only secondhand smoke, only secondhand vapor, or neither). Covariates included age, sex, ethnicity, family income, body weight, and height.Main Outcomes and MeasuresThe primary outcome was serum cotinine concentration, an objective biomarker of nicotine absorption. Geometric mean cotinine levels and 95% CIs were calculated using log-normal tobit regression, accounting for the complex survey design and weights.ResultsThe mean (SD) age of the 1777 children surveyed was 7.4 (2.6) years, 882 (49.6%) were female, and 531 (29.9%) had family incomes below the poverty level. Nicotine absorption, as indexed by serum cotinine level, was highest among children only exposed to secondhand smoke (0.494 μg/L μg/L; 95% CI, 0.386-0.633 μg/L), followed by those exposed only to secondhand vapor (0.081 μg/L; 95% CI, 0.048-0.137 μg/L), equating to 83.6% (95% CI, 71.5%-90.5%; P &amp;amp;lt; .001) lower nicotine absorption. Among children with no reported secondhand exposure, the geometric mean cotinine level was 0.016 μg/L (95% CI, 0.013-0.021 μg/L), or 96.7% (95% CI, 95.6%-97.6%; P &amp;amp;lt; .001) lower than for those with exposure to secondhand smoke. Results were similar after covariate adjustment.Conclusions and RelevanceIn this cross-sectional study of US children, nicotine absorption was much lower in children who were exposed to secondhand vapor vs secondhand smoke, but higher than in those exposed to neither. These findings suggest that switching from smoking to vaping indoors may substantially reduce, but not eliminate, children’s secondhand exposure to nicotine and other noxious substances.

Abstract:
Different services based on different switching techniques in wireless networks leads to drastic changes in the properties of network traffic. Because of these diversities in services, network traffic is expected to undergo qualitative and quantitative variations. Hence, assumption of traffic characteristics and the prediction of network events become more complex for the wireless networks. In this paper, the traffic characteristics have been studied by collecting traces from the mobile switching centre (MSC). The traces include initiation and termination time, originating node, home station id, foreign station id. Traffic parameters namely, call interarrival and holding times were estimated statistically. The results show that call inter-arrival and distribution time in this wireless network is heavy-tailed and follow gamma distributions. They are asymptotically long-range dependent. It is also found that the call holding times are best fitted with lognormal distribution. Based on these observations, an analytical model for performance estimation is also proposed.

Abstract:
The advancement of technical knowhow in wireless mobile phone clients and their inceptions from cloud server, have been implemented as versatile applications that utilize an optimal user experience. By using fabrication components in the user domain, we have yet to instill peripheral interfaces such us CPUs, memory and batteries in to achieving a personal computer machine usage in android devices. To empower the user interface as deployed in android applications, we must design a distributed computing environment that can be deployed in cloud servers. This thin client distributed architecture needs to be effective in ensuring a efficient android user experience . To resolve delays and latency from asynchronous mobile data usage, an effective deployment design must be implemented in mobilemobile environment, that uses Tcp/Ip packets in transferring from routable mobile switching server

Abstract:
The research examines the factors that affect customer churn (CC) in the Jordanian telecom industry. A total of 700 surveys were distributed. Cluster analysis revealed three main clusters. Results showed that CC and customer satisfaction (CS) were the key determinants in forming the three clusters. In two clusters, the center values of CC were high, indicating that the customers were loyal and SC was expensive and time- and energy-consuming. Still, the mobile service provider (MSP) should enhance its communication (COM), and value added services (VASs), as well as customer complaint management systems (CCMS). Finally, for the third cluster the center of the CC indicates a poor level of loyalty, which facilitates customers churn to another MSP. The results of this study provide valuable feedback for MSP decision makers regarding approaches to improving their performance and reducing CC.

Abstract:
Makalah ini membahas optimasi kinerja MSC (Mobile Switching Center) pada jaringan GSM.Penurunan kinerja MSC akan berdampak pada kualitas layanan telekomunikasi MS (Mobile Station). Salahsatu penyebab turunnya kualitas layanan jaringan adalah ketidak seimbangan layangan beban pada MSC.Untuk mengatasi masalah ini, dapat dilakukan dengan mengoptimasi ditribusi kapasitas beban jaringan padaMSC yang dikenal sebagai Repointing. Repointing merupakan proses koneksi dan tranfer data MGw dari satuMSC-S ke lain MSC-S. Studi kasus yang diamati adalah daerah Jabodetabek, dengan target repointing daerahJampang, Karawang, Ijah, Kedaton. Daerah ini dilayani oleh 6(enam) MSC (MSC21, MSC22, MSC23, MSC28,MSC29 and MSC30). Studi pada makalah ini difokuskan pada nilai CP Load (Central Processing Load), danPSR (Paging Success Rate), karena dua parameter ini menentukan kualitas layanan jaringan telekomunikasi.

Abstract Background The ability of people with type 1 diabetes mellitus (T1DM) to improve glycemic control depends on their ability to interpret and act on blood glucose results. We investigated applicants satisfaction when switching to blood glucose meters (BGMs) featuring rightest app via Bluetooth using their smartphones. Objective This study aimed to assess the feasibility of the app (rightest) and the participants satisfaction after using the app in 3 months interval by using UEQ -S score. Methods This is an observational study, conducted at the Pediatric and Adolescent Diabetes Unit, Children’s Hospital, Faculty of Medicine, Ain Shams University (PADU), on participants with T1DM(13-18 years old). The recruited participants (n = 20) with T1DM started using the “Rightest” app for 3 months. UEQ-S was used at the end of the study to asses the participants satisfaction. It consists of the two dimensions pragmatic quality (item 1–4) and hedonic quality (item 5–8). Each item is measured on a 7-point Likert scale with two opposite meanings ranging. Results 20 participants with T1DM, following up at PADU, used BGM with rightest app for 3 months. UEQ-S results revealed pragmatic total score (1.425) was above average while the hedonic total score was good(1.250) and the overall score was good(1.338) where -3 indicates extremely bad score while +3 indicates extremely good score. This indicates that they showed overall good satisfaction for mobile app using UEQ-S score. Conclusion This study demonstrated that switching to BGMs with mobile app showed good satisfaction after 3 month interval.

Abstract:
ABSTRACTWith the fast expansion of mobile devices and internet traffic, it is becoming critical to deliver dependable and robust services. HetNets and large networks are highlighted as probable solutions to the nearing capacity obstructions; however, they also present substantial challenges in terms of handover (HO) management. In cellular telecommunications, HO describes the procedure of moving an active call or data link from one base station (BS) to another. Whenever a mobile phone switches to another cell while a conversation is in progress, the MSC (mobile switching center) shifts the call to an alternate channel assigned to the new BS. The major objective of this work is to assist in how the HCP includes the functions of the 5G network, in which a modified deep learning architecture is introduced for predicting the NDR (network download rate) efficiently. In particular, a modified DNN architecture is introduced for this purpose. As a result, the proposed model attained a lower HO delay of 10.207 ms at a speed of 60 m/s, which surpasses the results of established techniques. From the analysis, it is proven that the proposed work efficiently increases the performance of the network without any interruption during transitions among cells.
