Segmentation requires the separation or division of an image into regions of similar properties. Image amplitude is the most basic attribute for image segmentation. Image texture and edges are also useful properties for the segmentation process. There is no standard approach for segmentation of an image; no single theory for image segmentation. Segmentation of an image is usually used to mark and determine boundaries and objects (curves, lines, etc.) in an image. More precisely, image segmentation is the process of labeling of every pixel in the image where pixels having the same properties have the same visual properties and share the same group. The result of segmentation process is a number of regions or segments that cover the whole image, or a number of extracted edges and contours of the image. All pixels in the same region are similar according to some characteristics or properties, such as texture, intensity, or color. In this paper a literature review of the various segmentation methods that are available for medical images is presented. Because of image segmentation importance, a set of image segmentation techniques namely; Thresholding techniques, Clustering techniques, Artificial Neural Networks, Edge based techniques, Region based techniques, Watershed, Graph based and Deformable models have been discussed and compared. The features and requirements of several freely and commercial software tools for image segmentation are clarified. The paper is ended by focusing on the novel trends on the topic.

This research work is concerned with the Planar ParallelManipulator (PPM). This investigation leads to a comparative studybetween the 2-RRR PPM which is a non-redundant PPM and 3-RRRPPM which is a redundant PPM. The main objective is to compareone type of PPM with another one that has one step ofconstruction’s upgrading with respect to the other PPM. Animportant issue for optimal design of these manipulators is relatedto their performance characterizations. These two PPMs areintroduced with their mechanism construction. Investigation ofcharacteristics of PPMs goes through the complexity of the directand inverse kinematics problems, which are solved using thesuggested and proper geometrical equations. The dexterousworkspace is geometrically obtained where the End-Effector (EE)can reach and illustrate some of its properties. In order to completethe study for these PPMs, the virtual work is determined, obtainedand used, to get the PPM characteristics using the dynamic model.Jacobian matrix has been determined and used. This research workis terminated not only by two kinematic characteristics mapsdexterity and manipulability - indices, but also with a dynamiccharacteristics map called dynamic index.

In this paper, the multiple scales perturbation (MSP) method is being used to examine controlling the compressor rotatingblade oscillations at superharmonic resonance. We apply position with velocity feedback controller on this dynamicalsystem to reduce its oscillations. The vibrational dual modes of are powerfully coupled with a linear ratio 1:1, so we haveapplied the controller to only one mode and the other coupled mode follows it. The overall nonlinear system behavior withand without control is studied. The system (pre and post control) is investigated via time response and other responsesto show the controller effect.

Implantable cardiac pacemaker is a standard medical device totreat heart rhythm disorders. In this paper, a new adaptivebackstepping controller is developed to enhance the performanceof dual-sensor pacemakers for regulating the heart rate, based onradial basis function neural networks. The robust design ofadaptive backstepping controller using Lyapunov functions allowsguaranteeing the stability and performance of the rate-adaptivepacing system for accurately accomplishing the heart rateregulation at different preset values. This developed controlsystem has been retrospectively tested on six datasets of twopatients with a pacemaker during three body activities of the rest,walking, and exercising. The resulting root mean square error(RMSE) and maximum error are less than 0.36 and 0.50 %,respectively. In addition, comparative results of this study showedthat the performance of developed backstepping controller issuperior to other pacemaker controllers in the previous studies.

A concurrency in database designed to implement multipletransactions on the same database simultaneously that mayproduce on a problem called transactions conflict. Theperformance improvement of web-based database transactionsis through applying concurrency. Previous proposals to applyconcurrency lead to huge problems such transactions conflict.Transactions Conflict leads to rollback some transactions frommultiple concurrent transactions to complete the others. Thispaper proposes an algorithm to solve this obstacle byimplementing locking on the cell level. This algorithm improvesthe throughput and committing transactions by about 42% and36% respectively.

In this paper, we present a proposed technique for imageencryption that is based on a marriage between Rubik’s cube (puzzle method) and a chaotic algorithm with its different modes (CBC, CFB, and OFB). The OFDM system will be tested with its versions (Fast Fourier transform OFDM (FFT-OFDM), Discrete Cosine Transform OFDM (DCT-OFDM), and Discrete Wavelet Transform OFDM (DWT-OFDM)). A comparative study among mixed encryption algorithms with images transmitted via different OFDM versions is presented. In the simulation experiments, the Peak Signal-to-Noise Ratio (PSNR) of the decrypted image at the receiver, histogram, deviation, and bit error rate (BER) sensitivity are used as evaluation metrics for the decrypted image qualit
