Production of Engineered Fabrics Using Artificial Neural Network–Genetic Algorithm Hybrid Model
The process of fabric engineering which is generally practised in most of the textile mills is very complicated, repetitive, tedious and time consuming. To eliminate this trial and error approach, a new approach of fabric engineering has been attempted in this work. Data sets of construction parameters [comprising of ends per inch, picks per inch, warp count and weft count] and three fabric pro...


Graphene Thermal Properties: Applications in Thermal Management and Energy Storage
We review the thermal properties of graphene, few-layer graphene and graphene nanoribbons, and discuss practical applications of graphene in thermal management and energy storage. The first part of the review describes the state-of-the-art in the graphene thermal field focusing on recently reported experimental and theoretical data for heat conduction in graphene and graphene nanoribbons. The e...
A design of a robust discrete-time controller
In this paper, we proposed a robust discrete-time controller. This control system, which is derived from the idea of the normalized plant, does not include plant parameters. Thus, we obtain a control system independent of plant parameters and that has the same structure as a conventional optimal servo control system. Simulation and experimental results show that the proposed method is fairly ro...


Detection of decoupled input/output pairs in multivariable systems
A method is proposed to detect if there is no coupling between an input and an output in systems operating in open-loop, that is, without a supervisory controller. The proposed technique is applicable to multiple input multiple output (MIMO) systems, whose intent is to detect no-model input/output (IO) combinations in a transfer matrix. Traditional approaches for selecting IO pairs are usually ...
Achievement of the best design for unequally spaced grounding grids
The configuration of grounding grids which are used to earth electrical substations could be equally or unequally spaced. Unequally spaced grids were introduced to improve the requirements of the grids such as grounding grid resistance (Rg ), ground potential rise (GPR), maximum touch voltage (Et ) and maximum step voltage (Es ) values. Also, unequal spacing can reduce the cost of the grids and...


Object-based VQ for image compression
In this paper, a vector quantization algorithm is proposed for image compression. The proposed algorithm composed of three phases, initialization, iterative and finalization. The initialization phase based on Max–Min algorithm. The iterative phase is an adaptive LBG algorithm. The finalization frees the codebook from redundancy. The LBG adapted to locate the codebook points to line up across ...
Towards Artificial Empathy
The design of artificial empathy is one of the most essential issues in social robotics. This is because empathic interactions with ordinary people are needed to introduce robots into our society. Several attempts have been made for specific situations. However, such attempts have provided several limitations; thus, diminishing authenticity. The present article proposes “affective development...

Toward development of a testbed for sustainable manufacturing
A growing number of manufacturing companies are treating sustainability as a strategic objective that will increase both their global competitiveness and their market share. To implement this objective, these companies must first assess, and then evaluate, their current sustainability performance. Assessments and evaluations are carried out by choosing among a variety of existing sustainability...
Derivation of a simplified relation for assessing aortic root pressure drop incorporating wall compliance
Aging and some pathologies such as arterial hypertension, diabetes, hyperglycemia, and hyperinsulinemia cause some geometrical and mechanical changes in the aortic valve microstructure which contribute to the development of aortic stenosis (AS). Because of the high rate of mortality and morbidity, assessing the impact and progression of this disease is essential. Systolic transvalvular pressure...

Designing an artificial pancreas architecture: the AP@home experience
The latest achievements in sensor technologies for blood glucose level monitoring, pump miniaturization for insulin delivery, and the availability of portable computing devices are paving the way toward the artificial pancreas as a treatment for diabetes patients. This device encompasses a controller unit that oversees the administration of insulin micro-boluses and continuously drives the pump...
Effective identification and localization of immature precursors in bone marrow biopsy
Abnormal localization of immature precursors (ALIP) aggregating and clustering in bone marrow biopsy appears earlier than that of bone marrow smears in detection of the relapse of acute myelocytic leukemia (AML). But traditional manual ALIP recognition has many shortcomings such as prone to false alarms, neglect of distribution law before three immature precursor cells gathered, and qualitative...

TDAL: Thoroughly Data Aggregation of Low Energy Devices in Secure Heterogeneous Wireless Sensor Networks
The heterogeneous wireless sensor networks (HWSNs), composed of multiple types of tiny devices (sensor nodes) with wireless communication capability and suffering from computational resources constrains, enable interacting with the physical world, like never before. Innovative applications are developed for security, industrial production, monitoring, and tracking, but theoretical assumptions o...
Application of the method of the specific forces in the mechanics of a viscoelastic collision between a solid body and a semi-space
The Mechanics of a viscoelastic collision between a solid body and a semi-space at impact at an arbitrary angle of attack have been examined in this paper. The radius of the contact area has been determined, using a geometry of mutual approach between two spherical bodies. It was proposed that the forces of viscosity and the forces of elasticity can be found by integration of the specific force...
