We propose a new serverless RFID protocol for authentication. Our scheme not only retains the original security agreement but also reduce the operations and increase the efficiency of the implementation. We also propose a RFID tag search protocol which is a new concept that we believe this tag search will be the future trend. This protocol has a better execution efficiency in comparison with other protocols.

This study comprises of the Genetic Algorithm (GA) approach to optimize a constrained portfolio for maximum return with an acceptable risk for Karachi Stock Exchange (KSE) assets. The portfolio selection model used in this paper is based on the classical Markowitz mean-variance theory enhanced with exogenous influence of floor and ceiling. The results are compared with MS Excel Solver (Solver). It is found that the model works well under the influence of a high probability of local minima.

For proper design of microwave components, such as filters, oscillators, mixers, and other microwave devices, the dielectric constant of the substrate must be known. Therefore, the main aim of this paper is to measure the dielectric constant of some Libyan materials, such as plastic and clay, to find out if they can be used as raw materials for many microwave devices that can be designed in the future. The measurements were done using two different methods, the microstrip ring resonator method and the two-layer stripline method. The paper includes the necessary designs of ring resonator, and the microstrip line, which were used in the measurements. A good result for the measurement of a dielectric constant of the material is obtained compared to the similar materials in the open literature.

Speeded Up Robust Features (SURF) is a state of the art computer vision algorithm that relies on integral image representation for performing fast detection and description of image features that are scale and rotation invariant. Integral image representation, however, has major draw back of large binary word length that leads to substantial increase in memory size. When designing a dedicated hardware to achieve real-time performance for the SURF algorithm, it is imperative to consider the adverse effects of integral image on memory size, bus width and computational resources. With the objective of minimizing hardware resources, this paper presents a novel implementation concept of a reduced word length integral image based SURF detector. It evaluates two existing word length reduction techniques for the particular case of SURF detector and extends one of these to achieve more reduction in word length. This paper also introduces a novel method to achieve integral image word length reduction for SURF detector.

This paper aims at development of low cost dynamic foot pressure scanner. To estimate the peak pressure points on the foot sole, a study was conducted on a healthy male group. In all, 8 subjects were placed for observation on EMED (from Novel Inc.) foot mat system at different clinics. The data, thus recorded, was analyzed using Novel-Win-Mask software and it is concluded that, on a single pressure head for a normal person, the deviation from mean value is not too much. Hence in case of a normal foot, the peak pressure points are heel, 1st, 3rd, 5th Meta tarsal head (MTH) and toe. Although 5 points for plantar pressure analysis look sufficient but one can add few more points to provide a complete coverage of pressure distribution on shoe sole. Using this data, shoe sole of different sizes were developed with 8 force sensing resistors (FSR) placed in each sole. The sole was connected to multi-channel Biopac MP100 data acquisition system (DAS) through an amplifier circuit. The USB interface is provided between DAS and the computer system. The data recording and analysis was performed using data acquisition software Acq. 3.7.3. The developed system is flexible and portable for field studies and also advantageous due to large memory size, dynamic recording of pressure and no fear of foot step modification. The data analysis can provide early information regarding diabetic foot ulceration and also could be used for shoe sole design.

The most important requirement of a power system for maintaining desired voltage profile and voltage stability is the existence of sufficient amount of reactive power reserve in the proper location of the power system. The requirement to locally generate reactive power, has made determining the installation point to be a requirement. In this paper some methods for identification of critical buses in power system are studied and results obtained from applying different compensateion methods on a test system are presented. In addition, the effect of application of wind generation on static voltage stability of the power system, are studied.

In the design of mobile electronics, power is one of the most difficult restrictions to overcome; and current trends indicate this will continue to be an issue in the future. Consumer electronic equipments are becoming small, portable devices that provide users with a wide range of functionality, from communication to music playing. The battery technology and the power consumption of the device limit the size, weight and autonomous lifetime. One promising alternative to batteries is to use parasitic energy dissipated in the movement of the wearer of device to power it. In this paper we designed a system included a rotary arm extending down from the sole, which ultimately drove the small electrical generator through a stepped-up gearbox. A one- way clutch mechanism was used to transmit torque to the gearbox. This allowed for additional spin following the initial impact of a step, also preventing lockup due to rotary inertia in the gears. The entire generator system was designed to fit in the heel of a standard running shoe, with the rotary arm compressing once during each heel strike.

This paper presents a practical implementation of a new strategy using the fuzzy logic for the detection and the diagnosis of broken bars in electrical induction machine. Motor Current Signature Analysis (MCSA) was used. The strategy rests on the follow-up (in amplitude and frequency) of the harmonics representing the defects of the broken bars, preparing and thus generating the adequate inputs for the treatment where the decision is made by fuzzy logic. The results obtained are good and it is capable to detect the correct number of broken bar.

In this paper, a simple yet efficient auto mode-hop ripple control structure for buck converters with light load operation enhancement is proposed. The converter, which operates under a wide range of input and output voltages, makes use of a state-dependent hysteretic comparator. Depending on the output current, the converter automatically changes the operating mode. This improves the efficiency and reduces the output voltage ripple for a wide range of output currents for given input and output voltages. The sensitivity of the output voltage to the circuit elements is less than 14%, which is seven times lower than that for conventional converters

Electronic voting is being used increasingly in several areas of work. The existing protocols and systems for voting are fraught with difficulties and flaws, which allow malicious users to tamper with the votes. Votes have to be unforgeable, anonymous and verifiable. In this paper, we suggest the use of 2 ID-Based signatures for an e-voting system. We describe a designated verifier ring signature, which will ensure both the security of the vote, as well as voter anonymity. In order for the voter to check if his/her vote has been taken into account, we provide a receipt for the voter, from the voting authority, using a new ID-Based designated verifier signature. The receipt will not allow the voter to reveal their vote to someone else, thus ensuring the security of the voter.
