Abstract:

In a remote user authentication scheme, a remote server verifies whether a login user is genuine and trustworthy, and also for mutual authentication purpose a login user validates whether the remote server is genuine and trustworthy. Several remote user authentication schemes using the password, the biometrics, and the smart card have been proposed in the literature. However, most schemes proposed in the literature are either computationally expensive or insecure against several known attacks. In this paper, we aim to propose a new robust and effective password-based remote user authentication

Abstract:

This paper proposes a general and systematic computational scheme for the dynamic motion of closed link mechanisms. The scheme can also be extended to multiple closed kinematic mechanisms. The closed link mechanism is essentially, treated as if it were cut at one of joints. The closed link mechanism is then equivalent to an open tree structure mechanism with constraints at the cut joint: By applying d’Alembert’s principle, the dynamic motion for the equivalent open tree structure mechanism with constraints is established. Based on the constraints condition of the original closed link mechanism

Three chemical kinetic mechanisms of methane combustion were tested and compared using the internal combustion engine model of Chemkin 4.02 [1]: one-step global reaction mechanism, four-step mechanism, and the standard detailed scheme GRIMECH 3.0. This study shows good concordances, especially between the four-step and the detailed mechanisms in the prediction of temperature and main species profiles. But reduced schemes were incapables to predict pollutant emissions in an internal combustion engine. The four-step mechanism can only predict CO emissions but without good agreement.

Abstract:

The transforming mechanism of pumping units is a four-link articulated mechanism, made according to symmetrical and asymmetric kinematic schemes. With a symmetrical scheme, the center of rotation of the crank is on a straight line passing through the points corresponding to the extreme positions of the connecting rod and balancer articulation. All other cases correspond to the asymmetric scheme. Currently, in accordance with the existing methodology for designing a converting mechanism of a symmetrical circuit, the kinematic ratios r/k and r/l are used as initial data - the ratio of the crank

Abstract:

The goal of this article is to analyse the scheme of arrangement as a debt restructuring tool in India and the extent to which it has been utilised. It finds that the scheme has been used sparingly for debt restructuring in India, and primarily in large and complex transactions. This is contrary to jurisdictions such as the United Kingdom and Singapore that have witnessed a rise in the use of this mechanism. This trend clearly indicates that the presence of an efficient restructuring mechanism in the legal rules is by itself inadequate to ensure its full utilisation. Apart from law on the stat

Abstract:

Signcryption is a relatively new way to achieve confidentiality and authentication simultaneously. Before the advent of signcryption the approach was to first encrypt and then to sign the message, but this scheme had more computational cost and communication overhead. Many signcryption schemes have been developed and implemented so far, but differ in security attributes they provide and computational cost they incur. This paper explains the mechanism of signcryption and analyzes the different cryptographic approaches which can be used along with signcryption. It also provides a glimpse of diff

Abstract:

Most of the arm lifts used in today’s industry are designed and manufactured based on the scissor mechanism. Such schemes have one drawback: when the mechanism is raised, their connection points with the base and the movable platform narrow, which leads to a let-down in its stability. This article proposes a new scheme for the lifting device, which eliminates the above disadvantage of scissor schemes. In the scheme developed by the authors, the joints connecting the mechanism to the moving platform and the base are fixed, which means that the distance between the connection points does not cha

As conventional public-key settings, ID-based public-key settings have to offer a revocation mechanism to revoke misbehaving or malicious users.

Abstract:

The paper presents two kinematic schemes of the reverse driving mechanism on CVT’s, the first one for rear-wheel drive, and the second one for front-wheel drive. For the first kinematic scheme, the reverse driving mechanism consists of a planetary cylindrical gear set and a multi-disk brake. In order to achieve a better efficiency for reverse driving, the authors propose a new kinematic structure of a planetary cylindrical gear mechanism, simpler than the existing designs. While describing a synthesis of the new kinematic solution, special attention was granted to maintaining the advantages of

Abstract:

Based on the directed relation graph with error propagation (DRGEP) reduction method, a detailed mechanism consisting of 119 species and 527 reactions for n-decane was simplified. As a result, a skeletal mechanism comprising 32 species and 73 reactions was derived. Subsequently, the quasi-steady state approximation (QSSA) reduction method was employed to further simplify the skeletal mechanism, resulting in a reduced mechanism with 18 species and 14 global reactions. A comparison between the reduced mechanism, skeletal mechanism, and detailed mechanism revealed that the reduced and skeletal me

Due to the unique characteristics of blockchain, such as decentralization, anonymity, high credibility, and nontampering, blockchain technologies have become an integral part of public data platforms and public infrastructure. The communication between the stakeholders of a given blockchain can be used as a carrier for covert communication under cover of legal transactions, which has become a promising research direction of blockchain technology. Due to the special mechanism of blockchain, some traditional blockchain covert communication schemes are not mature enough. They suffer from various

Quality of service (QoS)-aware data gathering in static-channel based underwater wireless sensor networks (UWSNs) is severely limited due to location and time-dependent acoustic channel communication characteristics. This paper proposes a novel cross-layer QoS-aware multichannel routing protocol called QoSRP for the internet of UWSNs-based time-critical marine monitoring applications. The proposed QoSRP scheme considers the unique characteristics of the acoustic communication in highly dynamic network topology during gathering and relaying events data towards the sink.

Abstract. The optimal choice of the planetary boundary layer (PBL) parameterization scheme is of particular interest and urgency to a wide range of scholars, especially for many works involving models. At present, there have been many works to evaluate the PBL schemes. However, little research has been conducted into a more comprehensive and systematic assessment of the performance capability of schemes in key regions of China, especially when it comes to the differences in the mechanisms of the schemes themselves, primarily because there is scarcely sufficient observational data, computer res

Abstract:

Vehicular ad hoc networks (VANETs) have been widely researched in recent years. VANETs are used mostly for road safety and traffic efficiency; therefore, it is imperative that the communication between vehicles is rapid and secure in a VANET environment. In the present study, bilinear pairings were used to construct a complete message authentication scheme. This scheme provided the following features: (1) vehicle or roadside unit (RSU) parameters were determined via a hierarchical protocol, which prevented potentially a large computational overhead for a single node; (2) message broadcasts and

Abstract:

The urban intersection signal decision-making in traditional control methods are mostly based on the vehicle information within an intersection area. The far vehicles that have not reached the intersection area are not taken into account, which results in incomplete information and even incorrectness in decision-making. This paper presents an intersection signal control mechanism assisted by far vehicle information. Using the aid of real-time information collection for far vehicles through vehicular ad hoc networks (VANETs), we can consider them together and calculate the accumulative waiting

This paper aims to improve energy efficiency of IEEE 802.11 wireless local area networks (WLANs) by effectively dealing with idle listening (IL), which is required for channel sensing and is unavoidable in a contention-based channel access mechanism. Firstly, we show that IL is a dominant source of energy drain in WLANs and it cannot be effectively alleviated by the power saving mechanism proposed in the IEEE 802.11 standard. To solve this problem, we propose an energy-efficient mechanism that combines three schemes in a systematic way: downclocking, frame aggregation, and contention window ad

Therefore, for an experimental pressure control model, a fractional order PID controller with intelligent fuzzy tuning was constructed and its results were calculated through simulation.
