For the adjacency matrix A of a graph G, a number λ is an eigenvalue of G if for some non zerovector X, AX=λX. The vector X is called the eigenvector corresponding to λ. The eigenvalues are exactly those numbers λ that make the matrix A-λI to be singular. All eigenvectors corresponding to λ forms a subspace Vλ; the dimension of Vλ is equal to the multiplicity of λ. A graph G is a Smith graph if 2 is an eigenvalue of the adjacency matrix A of G, a λ-weighting technique is introduced and applied to characterize some classes of Smith graphs as well as to study their nullities and the nullity of vertex identification of such graphs. We also have proved that under certain conditions the vertex identification of some Smith graphs is a Smith graph.

A spectrophotometric method for determination of Ca in aqueous solution using 1-(2-pyridylazo)-2-naphthol (PAN) as color reagent based on the formation of Ca-PAN Complex at pH 12 and measuring absorbance at 550nm, with molar absorptivity of 1.70×104 L.mol-1cm-1 has been modified to a flow injection-spectrophotometric (FI) method. The modified FI method is rapid, accurate, precise, and with low operation cost. The linear range of 1-8ppm was obtained with average recovery of 103.46 and precision of 1.5-3.4%. The proposed FI method using PAN as a color reagent was applied satisfactorily for the assay of Ca in natural water, milk, yogurt and human serum.

this paper introduces a modified management system for smart electrical energy meter. The proposed smart meter has feature to inform the consumer about energy consumption, this feature serves energy consumption reduction by self-awareness of real consumption. The other important feature is to eliminating the difficulties by direct contact by employee and consumer to getting the reading of the conventional meter and also reduction of error in bill. The proposal system consists of two parts: client’s side part (the prepaid meters in consumer houses) and server side (electrical sub-station). The client part consists of an RFID reader, credit cards, GSM network, Arduino microcontroller and electronic meter. The system operates with high accuracy which could tell the user the amount of energy consumed at any moment and these results the user will be urged to rationalize energy consumption.

Cache memory is an important part in computer systems. In set associative cache memory each incoming memory block from the main memory into cache memory should be placed in one of many specific cache lines according to the degree of associativity. In case of all ways lines are fill, a replacement policy should be designed to indicate which line of that cache memory ways will be replaced. In this paper a LRU (Least Recently Used) replacement policy has been implemented in two different methods for reconfigurable cache memory using FPGA (Field-Programmable Gate Array) and programmed using VHDL (Very high speed IC Hardware Description Language). The tree based pseudo LRU replacement policy is much simple and requires less LRU array size than Conventional LRU because it needs only 7 bits for each cache line. While the conventional LRU is easier in implemented and also require only one unit to managing the LRU replacement policy.

The amount of digitized application is growing fast and continuously. As the result of such growth, professional, reliable and secure techniques for identifying people inside both real and virtual worlds are mandatory. In this paper, we present a fully automatic ear-based biometric system which needs no human intervention and can be used in a real-time manner. The proposed system aims to recognize people based on their ear shape extracted from a profile facial image which usually suffers from partial occlusion caused by hair and/or earrings. First, a cascaded classifier-based ear detection approach that uses Haar-like features is used to detect ears in profile images. Later, the process is followed by a novel ear recognition technique based on Shape Context descriptor. The results of testing the proposed approach on some of the standard datasets show promising results; for non-occluded images 100% recognition achieved while for the images where the ear was occluded by both hair and earring, the accuracy was 57%.

This work involves the design and implementation of a robotic hand controlled wirelessly to emulate human hand fingers motion. The design includes two circuits: transmitting and receiving. A glove and flex sensors are placed at the transmitting side while a robotic hand is sitting at the receiving side. Motion control signals are being exchanged wirelessly between the transmitting and receiving circuits via Bluetooth modules. Also, Arduino cards are implemented on both sides to control the servomotor of each robot finger. The robotic hand consists of five fingers designed using three-dimension 3D printer. Each finger has three degree of freedom (3-DOF) and it is controlled by one servomotor for actuating with angle of rotation from 0° to 180°. The forward and inverse kinematics for the index figure is derived mathematically for 3-DOF robot finger, and the third order polynomial trajectory motion is simulated to test the robot kinematics by using MATLAB Simulink. The physical tests show that the hand motion serves concisely for catching objects with a maximum distance range for connection of 37 meters. Also, the simulation results show exact inverse kinematic using the equations derived from the forward kinematic. This robotic hand can be applied in the areas where the intervention of humans may cause danger on their health due to chemical, biological and radiological nature.

The physical properties (density, viscosity, and dielectric constant) of five different compositions (0, 10, 20, 30, and 40%) of ethylene glycol-water mixtures have been measured at nine temperatures from (278.15 to 318.15 K) which were utilized to calculate the standard potentials of the Silver-Silver Chloride electrode and the mean activity coefficient of ten different concentration of HCl ranged from (0.01-0.1m). The modeling of the investigated system was made based on an extended Debye-Hückel equation, using Galvanic cell without liquid junction pt, H2(g, 1atm)│HClm), EG+water|AgCl(s),Ag. The standard potential at different temperatures were utilized to calculate the standard thermodynamic quantities ∆G °, ∆H °, and ∆S ° for the cell reaction. The results discussed in concerning with acid-base properties, solute-solvent interactions and the breakdown of the water structure on the addition of ethylene glycol.

This study describes a representation of gait appearance for the purpose of person identification and classification. The gait representation is based on wavelet 5/3 lifting scheme simple features such as features extracted from video silhouettes of human walking motion. Regardless of its effortlessness, this may lead us to say that, the resulting feature vector contains enough information to perform well on human identification and gender classification tasks. We found out the recognition behaviors of different methods to total features over time functions under different recognition tasks. In addition to that, we provide results of gender classification based on our gait appearance features using a (C4.5 algorithm). So, the result of classification rate for CASIA - B gait databases is 97.98% and the result of recognition rate for OU-ISIR gait Database Large Population Dataset is 97.5%, these results have been obtained from gender classification data. Gait database demonstrates that the proposed method achieves better recognition performance than the most existing methods in the literature, and particularly under certain walking variations.
