Published: November 2019

Abstract
In response to the demand of the development of energy Internet for the comprehensive perception and wide interconnection of massive data of power system, the concept of ubiquitous power Internet of things(UPIoT), which comes from the deep integration of Internet of things technology and smart grid, has been put forward, becoming an important content and key link in the transformation and upgrading of power grid enterprises. The centralized computing mode previously adopted by smart grid can no longer meet the needs of large-scale computing and rapid response, so the ubiquitous power Internet of things should adopt the operation mode combining centralized computing and distributed computing. Firstly, this paper discusses the basic concepts and main characteristics of ubiquitous power Internet of things. Based on edge computing, this paper constructs the basic architecture of substation internet of things composed of perception layer, network layer, platform layer and application layer. Secondly, it discusses the key technologies in the construction of substation internet of things, and finally analyzes the specific application of edge computing in the construction of substation internet of things.

Published: November 2019

Abstract
The purpose of work is development of the model and carrying out numerical calculations of cooling of thin jets from hydrogen and deuterium as applicable to installations for receiving cryogenic monodisperse targets. For this purpose the model of the expiration of a cryogenic jet to the low pressure area is created, the change of surface temperature and an internal jet part at different external parameters with respect to time is investigated through numerical solutions in PHOENICS software. Dependences of temperature change of liquid jets from hydrogen and deuterium along jet surface and on radius depending on jet diameter, speed, initial jet temperature and pressure in the working chamber of installations for receiving cryogenic monodisperse targets are carried out. The basic possibility of creation of high-speed cryogenic monodisperse targets is shown. According to calculations, at input of thin liquid jets of hydrogen or deuterium with a speed up to 100 m/s in the working chamber with low pressure, jets at distance up to 1 mm do not manage to freeze and can be broken into monodisperse drops. Drops are cooled and become granules due to evaporation. The developed model, the program for determination of parameters of steady monodisperse disintegration of liquid cryogenic jets and results of numerical calculations can be used during creation of installations for receiving high-speed cryogenic monodisperse targets.
Long-Duration Thermal Decomposition of Waste based upon existing coke and plasma technology
Authors: Glazkov V V , Balashov A Y 
Published: November 2019

Abstract
The current global problem of accumulation of municipal solid waste (MSW) and a possible way to solve it is considered. To date, there are different ways to treat MSW: recycling (processing), incineration and disposal. Each of them has its advantages and disadvantages. Waste disposal is the least environmentally safe method, but now it is the main one in Russia because of its availability. This article proposes a scheme for recycling MSW, which is based on already existing coke, energy and plasma technologies. Within the scheme thermal destruction of waste is carried out in a coke battery, and the subsequent melting of the residue is carried out using plasma technologies (in an electric arc furnace or in an open bucket with heating from the plasmatron). The plasma module, in which the melting takes place, can be implemented both with the circuit in question and attached to an existing incinerator. The result of melting is a low-grade stone that does not need to be buried. Gases released from MSW in the process of thermal destruction, after deep cleaning, are used to generate electricity. The source of thermal energy required for the operation of the proposed scheme for recycling solid waste is thermal power plants using natural gas as fuel. The interaction between the flue gases passing through the coke oven battery and leaving the TPP with coke oven gases is excluded due to the design features of the coke oven battery. This allows you to dramatically reduce the amount of gas to be deep cleaning, which significantly reduces the cost of cleaning equipment. The use of coke-oven batteries of modern design minimizes environmental pollution. The article assesses the energy consumption for the implementation of the proposed scheme for a plant processing 100 thousand tons of solid waste per year. The source of thermal energy for which is the standard unit of thermal power plants with a capacity of 500 MW. It is shown that working in conjunction with a waste recycling plant changes the heat balance of TPPs by no more than 10%.

Abstract
A modified rectangular microstrip is introduced and presented as an applicator for hyperthermia cancer procedure. SEMCAD X solver is used as the simulation tool to investigate the rectangular microstrip, which is applied and radiated to the breast phantom. The research is carried out in order to enhance the penetration depth, which is up to 100mm and improve the focusing capability, which means that to reduce the unwanted hot spots at the vicinity area of the treated tissue. The specific absorption rate (SAR) distributions of 1 and 10 g weights of breast tissue are obtained as simulation results. The operating frequency utilized for the study is 915 MHz, with three operating powers of 10, 100, and 200 W. Beside rectangular, a circular microstrip applicator with microstrip feed line is also simulated in order to determine which shape of the microstrip applicator presented the greatest results in term of the depth penetration and focusing capability. As expected, the greatest SAR is provided by the microstrip applicator with rectangular shape. By that, the rectangular microstrip applicator is further explored and modified. From the outcomes, the rectangular microstrip with structure 4 presents the utmost specific absorption rate deposition; the required penetration depth is achieved, and focusing is enhanced with minimal unwanted hot spots at the vicinity of the treated area.

Abstract
Development of reconstructed three dimensional (3D) model of bones has successfully emerged from time to time. It is used in many engineering applications especially by researchers to help them in the simulation process through finite element analysis (FEA). Besides, the 3D model can also be used by surgeons with the help of engineers, in improving their pre-surgical planning and designing of patient-specific implants or surgical instruments. Focusing on the femur, this paper proposes a method in developing a reconstructed three-dimensional femoral bone model and verifying it through analysis by using the Finite Element Method. Load of 600N was applied on the most proximal point of the femoral head under axial loading. The strain value observed in the model were 0.35 mε, 0.242 mε, and 0.146 mε. These values were slightly higher than the value measured in cadaveric specimen in the previous study, but it showed the same pattern. Hence, it can be concluded that the development method is reliable.

Published: November 2019

Abstract
This study proposes a modified initialization approach for the conventional FCM, namely FCM with guided initialization. The FCM with guided initialization was implemented to segment the relevant regions in the breast histopathology images. The initialization method to select initial centers is based on the Cyan (C) channel histogram. Area Overlap Measure (AOM) and Combined Equal Importance (CEI) were used to evaluate the performance of the proposed FCM with guided initialization. The obtained AOM and CEI for the overall dataset achieved promising results: 0.89 in AOM and 0.88 in CEI. When comparing the number of iterations required to complete the proposed FCM clustering algorithm, the FCM with guided initialization is found to be effective in reducing the search space by showing a lower number of iterations.

Abstract
Living mammalian especially European cats will face some problems when traveling from cold ambient in Europe to hot ambient country. Some of the problems are, these cats will become panting when exposed to the high temperature of ambient for a short term. Also, for a long term exposed to high temperature, the cats will experience heat stress and hair loss. The objectives of this study are on cat thermal comfort, cooling load for cat compartment, and analysis of air flow to achieve the desired temperature for the cat compartment using CFD simulation. In this study, three parts of analysis will be considered in CFD simulations which are the thermal distribution for four Peltier plates with aluminium heat sink using ANSYS Transient Thermal, air flow in the ducting to a cold heat sink, and air flow distribution in cat compartment using ANSYS Fluent. The temperature for the Persian cat’s thermal comfort is around 20-25°C. Cooling load gain from designed portable cat compartment with the desired space is 177 W. By ANSYS Transient Thermal, time taken for heat sink change from 22°C to 12°C is around 200-250 seconds. Then, by using ANSYS Fluent, the temperature of initial air temperature in the ducting when flow through a cold heat sink was changed from 27.15°C to 20.93°C by simple cooling. Next, the average air temperature in the cat’s compartment is 23.83°C that achieved average thermal comfort for mammal or Persian cat which is 20-25°C of dry bulb temperature. However, the study only focuses on steady-state dry air simple cooling analysis only with the laminar flow as a preliminary result by CFD simulation before build the actual portable cat compartment. The dry air simulation can be assumed similar as humid air for simple cooling process only proved by the comparison of the same cooling capacities values towards the different value of absolute humidity.

Abstract
An operation theatre (OT) is a special room inside the hospital where medical surgery is carried out by a surgeon with the help of medical personnel. Technical standards or requirements which have been set for heating, ventilation and air conditioning (HVAC) inside an operation theatre is important not only for the comfort of surgeon, patient, and medical personnel, but also to reduce the risk of surgical site infection during surgery. This research focus on Minor Operation Theatre (MOT) which is dental surgery room at Universiti Malaysia Perlis Health Centre with room dimensions of 2.89 m(H)×3.12 m(W)×3.4 m(L) is used for numerical analysis. The air flow supplied to the MOT is from single unit air-conditioning system. Computational Fluid Dynamics (CFD) analysis is a part of an investigation to determine the air flow and temperature distribution inside the MOT. A simulation conducted by using ANSYS Fluent only consider dry air inside MOT. Therefore, the main aim of this research is to compare and analyze the simulation of dry air conducted with previously obtained experimental data of humid air distribution inside the MOT. The comparison of humid and dry air temperature throughout the MOT shows that the difference is 25.3%. The average temperature of humid air inside the MOT is 21.8 °C while for dry air is 16.3 °C. Moreover, the cooling capacity of humid air and dry air are 2.23 kW and 1.64 kW respectively. Thus, the difference between humid air and dry air-cooling capacity is 26.5%. However, the dry air simulation and humid air simulation is the same if only the process is considered as simple cooling.

Abstract
The IoT fall detection system detects the fall through the data classification of falling and daily living activity. It includes microcontroller board (Arduino Mega 2560), Inertial Measurement Unit sensor (Gy-521 mpu6050) and WI-FI module (ESP8266-01). There total ten (10) subjects in this project. The data of falling and non-falling (daily living activity) can be identified. The falling is the frontward fall, while the daily living activity includes standing, sitting, walking and crouching. K-nearest neighbour (k-NN) classifiers were used in the data classification. The accuracy of k-NN classifiers were 100% between falling and non-falling class. The feature was selected based on the percentage of accuracy of the k-NN classifier. The features of the Aareal.z (97.14%) and Angle.x (97.24%) were selected due to the good performance during the classification of the falling and non-falling class. The performance of the Aareal.z (58.41%) and Angle.x (57.78%) were satisfactory during the sub-classification of the non-falling class. Hence, the feature of Aareal.z and Angle.x were selected as the features which were implemented in the IoT fall detection device.
