Full textAbstract:
In this paper, we propose the first ARIA block cipher on both MSP430 and Advanced RISC Machines (ARM) microcontrollers. To achieve the optimized ARIA implementation on target embedded processors, core operations of ARIA, such as substitute and diffusion layers, are carefully re-designed for both MSP430 (Texas Instruments, Dallas, TX, USA) and ARM Cortex-M3 microcontrollers (STMicroelectronics, Geneva, Switzerland). In particular, two bytes of input data in ARIA block cipher are concatenated to re-construct the 16-bit wise word. The 16-bit word-wise operation is executed at once with the 16-bit instruction to improve the performance for the 16-bit MSP430 microcontroller. This approach also optimizes the number of required registers, memory accesses, and operations to half numbers rather than 8-bit word wise implementations. For the ARM Cortex-M3 microcontroller, the 8×32 look-up table based ARIA block cipher implementation is further optimized with the novel memory access. The memory access is finely scheduled to fully utilize the 3-stage pipeline architecture of ARM Cortex-M3 microcontrollers. Furthermore, the counter (CTR) mode of operation is more optimized through pre-computation techniques than the electronic code book (ECB) mode of operation. Finally, proposed ARIA implementations on both low-end target microcontrollers (MSP430 and ARM Cortex-M3) achieved (209 and 96 for 128-bit security level, respectively), (241 and 111 for 192-bit security level, respectively), and (274 and 126 for 256-bit security level, respectively). Compared with previous works, the running timing on low-end target microcontrollers (MSP430 and ARM Cortex-M3) is improved by (92.20% and 10.09% for 128-bit security level, respectively), (92.26% and 10.87% for 192-bit security level, respectively), and (92.28% and 10.62% for 256-bit security level, respectively). The proposed ARIA–CTR implementation improved the performance by 6.6% and 4.0% compared to the proposed ARIA–ECB implementations for MSP430 and ARM Cortex-M3 microcontrollers, respectively.

Microcontroller MSP430 is used to control the SSR switches to supply a very high current. PC is interfaced to the supercomputer for computations. SSR and contactor switches are used to pass the current. Capacitor discharge system is also used to supply a very high current around 170-200A. High current is passed to the sample specimen placed inside the heater which needs to be heated at a very high temperature. The current pulse is generated by the capacitor discharge system. Power supply for regular heater is suspended temporarily and capacitor is allowed to discharge using the Capacitor discharge heating. This is achieved by the instructions through the computer to the microcontroller. Current injection at the particular instant is done with the help of a software by initiating an interrupt from the computer. The interrupt pin of the microcontroller becomes high by this and the operation is initiated correspondingly. Thus the MSP430 receives the command to give the necessary pulse of current for heating at the required time. Feedback is received with regard to the position of the switches whether the particular SSR is ON or OFF. Injection of power depends on the corresponding switch positions by giving the necessary instructions by the computer.

Full textAbstract:
A novel, active cell balancing circuit and charging strategy in lithium battery pack is proposed in this paper. The active cell balancing circuit mainly consists of a battery voltage measurement circuit and switch control circuit. First, all individual cell voltages are measured by an MSP430 microcontroller equipped with an isolation circuit and a filter circuit. Then, the maximum cell voltage difference is calculated by subtracting the minimum cell voltage from the maximum cell voltage. When the maximum cell voltage difference exceeds 0.05 V, the balancing action starts to carry on. The MSP430 microcontroller output controls signals to close the switches corresponding to the battery cell with the maximum voltage. At this time, the balancing charge power performs a balancing charge for other batteries, except for the one that is switched on. In addition, a three-stage balancing charge strategy is also proposed in this paper to achieve the goal of speedy charging with balancing action. In the first stage, a 0.5 C balancing current is used to perform pre-balanced charging on all battery cells until the maximum cell voltage difference is less than 0.05 V, which is required for entry to the second stage of charging. In the second stage, constant current charging of 1 C, coupled with 0.2 C balancing current charging is carried out, until the maximum battery cell voltage reaches 4.2 V, which is required for entry into the third stage of charging. In the third stage, a constant voltage charging is coupled with 0.2 C balancing current charging, until the maximum battery cell voltage reaches 4.25 V, which is required to complete the balancing charge. The imbalance of power between the battery cells during battery pack charging, which reduces battery charging efficiency and battery life, is thus effectively improved. In this paper, a six-cells-in-series and two-in parallel lithium battery pack is used to perform a balancing charge test. Test results show that the battery cells in the battery pack are capable of quickly completing a balancing charge under different initial voltages, the maximum voltage difference is reduced to within the range of 0.05 V, and the total time required for each balancing charge is approximately 3600 s.

The necessity for adequate security of lives and properties cannot be overemphasized. Tackling insecurity in an effective manner calls for active computer-based researches and solutions. Essentially a security system is designed to help detect intrusion and prevent unauthorized access. These security threats are tracked by installing various security access doors and alarm systems. Findings have shown that many access doors use either password or biometric form of authentication separately which are easily compromised. This paper presents a two level automated access control for door security with mobile alert system, powered by a 5V, 6000mAH battery. In addition a multi factor authentication using biometrics (fingerprint) and password was also used to enhance access control for this system. A mobile phone call alert and alarm system was uniquely included to this design to notify owners of the presence of an intruder when multiple attempts of incorrect login credentials are presented to the system over a short period of time. The program for the microcontroller was written in C language. This paper concluded that the use of multi factor authentication with mobile phone call alert will help improve the security for access doors used in banks, residential buildings, hospitals, military properties and other institutions and where confidentiality and restrictions are needed.

During the past decade, many countries launched ambitious Electronic Health Record (EHR) programs with the objective to increase the quality of care while decreasing its cost. Pervasive healthcare aims itself at making healthcare information securely available anywhere and anytime, even in disconnected environments (e.g., at patient home). Current server-based EHR solutions badly tackle disconnected situations and fail in providing ultimate security guarantees for the patients. The solution proposed in this paper capitalizes on a new hardware device combining a secure microcontroller (similar to a smart card chip) with a large external Flash memory on a USB key form factor. Embedding the patient folder as well as a database system and a web server in such a device gives the opportunity to manage securely a healthcare folder in complete autonomy. This paper proposes also a new way of personalizing access control policies to meet patient’s privacy concerns with minimal assistance of practitioners. While both proposals are orthogonal, their integration in the same infrastructure allows building trustworthy pervasive healthcare folders.

Toddler development stage is an important thing to always follow-up. A child is not the same as a miniature adult. Small children are still experiencing a process of growth and development. These two processes are important for the child's future in terms of physical and brain development. Delays or abnormalities at the stage of toddler development can have a negative impact on the toddler. This is the reason why knowing the stage of toddler development becomes a very important thing. Monitoring toddler development can be more practical by utilizing a combination of technology between microcontroller control and database usage as a result of monitoring. Monitoring conducted on toddlers can include monitoring the development of body weight, monitoring body temperature, and monitoring the toddler's heart rate. This microcontroller can process data generated by load cell, temperature sensor and heartbeat sensors to be processed and displayed in real time using the web with a MySQL database. Users who have logged in can access data on the development of body weight, body temperature, and heart rate of toddlers with good and organized records wherever and whenever. So that toddler development can be known easily.

Keyless lock gate with fingerprint access has many advantages over traditional systems such as passwords. Therefore, fingerprint identification represents the main part, which require that system is cheap, practical, easy to use and allows fast and securely. This paper discusses the design and implementation with real time model of a practical lock gate system for the achievement of high security by using fingerprint purification to control the mechanism of opening doors in banks, warehouses, laboratories and places of interest. In this paper, the microcontroller technology in the Ardonio board was used with an optical sensor to take the fingerprint, convert it into digital data, and insert it into a definition window to unify all input data and store it for use when compared to the system experience. After obtaining the result of the comparison, the appropriate commands are prepared for operating the servo of the lock mechanism for the doors used. In the testing of the system, the results are very accurate. The system also has other advantages such as small size and low power required for operation and ease of use. </span>

One of the most important issues in accessible science education is creating a laboratory workspace accessible to blind students or students with visual impairments (VI). Although these students are often provided access to the science lectures, they are usually denied full participation in hands-on laboratory work. Current solutions to this problem focus on providing special accommodations such as asking sighted lab partners to complete the hands-on work. Although the accessibility of laboratory devices in modern science education has been improved in recent years, students with VI often remain passive learners. In this work, we developed a new artificial intelligence tool, the MSU Denver Virtual Lab Assistant (VLA), using Amazon Web Services (AWS), Amazon Alexa Skills Kit (ASK), Alexa smart speaker, and a microcontroller (Raspberry Pi). The VLA can be used as a virtual assistant in the lab in combination with other access technologies and devices. The VLA allows students with VI to perform the hands-on laboratory work by themselves simply using voice control. The VLA can be accessed through any smartphone or Amazon Echo device to assist general science lab procedures. The VLA is designed to be applicable to different science laboratory work. It is also compatible with other common accessible electronic devices such as the Talking LabQuest (TLQ). We believe that the VLA can promote the inclusion of learners with VI and be beneficial to general accessible science education work.

Agricultural research involves study of the complex soil–plant–atmosphere–water system, and data relating to this system must be collected under often-harsh outdoor conditions in agricultural environments. Rapid advancements in electronic technologies in the last few decades, as well as more recent widespread proliferation and adoption of electronic sensing and communications, have created many options to address the needs of professional, as well as amateur, researchers. In this study, an agricultural research project was undertaken to collect data and examine the effects of different agronomic practices on yield, with the objectives being to develop a monitoring system to measure soil moisture and temperature conditions in field plots and to upload the data to an internet website. The developed system included sensor nodes consisting of sensors and electronic circuitry to read and transmit sensor data via radio and a cellular gateway to receive node data and forward the data to an internet website via cellular infrastructure. Microcontroller programs were written to control the nodes and gateway, and an internet website was configured to receive and display sensor data. The battery-powered sensor nodes cost $170 each, including electronic circuitry and sensors, and they were operated throughout the cropping season with little maintenance on a single set of batteries. The solar-powered gateway cost $163 to fabricate, plus an additional cost of $2 per month for cellular network access. Wireless and cellular data transmissions were reliable, successfully transferring 95% of sensor data to the internet website. Application of open-source hardware, wireless data transfer, and internet-based data access therefore offers many options and advantages for agricultural sensing and monitoring efforts.
