Energy Management Scheme for an EV Smart Charger V2G/G2V Application with an EV Power Allocation Technique and Voltage Regulation
Year: 2018

The increasing penetration of electric vehicles (EVs) in the distribution grid has established them as a prospective resource for ancillary services. These services require adequate control strategies for prompt and efficient operation. In this study, an energy management scheme (EMS) has been proposed to employ an off board EV smart charger to support the grid during short term variance of renewables and reactive load onset. The scheme operates by calculating power references for the charger instantaneously. The EMS incorporates a proportional power division methodology, proposed to allocate power references to the individual EVs connected to the charger DC bus. This methodology considers the state of charge and battery sizes of the EVs, and it can aggregate energy from various types of EVs. The proposed scheme is compared with another power allocation method, and the entire EMS is tested under the scenarios of power mismatch and voltage sag/swell events. The results show that the proposed scheme achieves the goal of the aggregation of EVs at the charger level to support the grid. The EMS also fulfills the objectives of voltage regulation and four quadrant operation of the smart charger.
PERTANGGUNGJAWABAN PIDANA KORPORASI SUATU GAGASAN UNTUK KORPORASI SEBAGAI LEGAL PERSON YANG MANDIRI DALAM PERTANGGUNGGUNGJAWABAN PIDANA KORPORASI
Year: 2017

Penelitian ini menjelaskan konsep pertanggungjawaban korporasi dalam hukum pidana yang merekonstruksi teori dan doktrin hukum lama untuk diterapkan dalam korporasi. Hukum pidana mengesampingkan untuk mengadaptasi prinsip personalitas korporasi menyebabkan konsep pertanggungjawaban korporasi bergantung pada konsep personalitas dalam hukum pidana.Tatanan praktis dalam pertanggungjawaban pidana korporasi akan selalu lepas dari jeratan hukum oleh karena penerapan konsep personalitas pada penegakan hukumnya. Penelitian ini menggunakan metode penelitian kualitatif dengan berbasis data kepustakaan serta emperis dengan melihat fakta fakta kasus yang terjadi. Penelitian ini menunjukan pertama, dalam penerapan pertanggungjawaban pidana korporasi, korporasi dianggap sebagai entitas yang sama dengan personal yang ada didalamnya, sehingga korporasi tidak dapat menjadi subyek hukum yang melakukan tindak pidana. Kedua, melalui kritik kesalahan dalam ajaran normatif seyogyanya korporasi dapat dipertanggungjawabkan tanpa mengaitkan korporasi dengan pengurus yang mengelola korporasi.

Multichannel Speech Separation and Enhancement Using the Convolutive Transfer Function
Venue: IEEE/ACM Transactions on Audio, Speech, and Language Processing
Year: 2019

This paper addresses the problem of speech separation and enhancement from multichannel convolutive and noisy mixtures, <italic>assuming known mixing filters</italic> We propose to perform speech separation and enhancement in the short time Fourier transform domain using the convolutive transfer function (CTF) approximation. Compared to time domain filters, the CTF has much less taps. Consequently, it requires less computational cost and sometimes is more robust against the filter perturbations. We propose three methods: 1) for the multisource case, the multichannel inverse filtering method, i.e. the multiple input/output inverse theorem (MINT) is exploited in the CTF domain; 2) a beamforming like multichannel inverse filtering method applying the single source MINT and using power minimization, which is suitable whenever the source CTFs are not all known; and 3) a basis pursuit method, where the sources are recovered by minimizing their <inline formula><tex math notation="LaTeX"\ell _1$/tex math>/inline formula> norm to impose spectral sparsity, while the <inline formula><tex math notation="LaTeX"\ell _2$/tex math>/inline formula> norm fitting cost between microphone signals and mixing model is constrained to be lower than a tolerance. The noise can be reduced by setting this tolerance at the noise power level. Experiments under various acoustic conditions are carried out to evaluate and compare the three proposed methods. Comparison with four baseline methods beamforming based, two time domain inverse filters, and time domain Lasso shows the applicability of the proposed methods.
Conventional Counterforce Dilemmas: South Korea's Deterrence Strategy and Stability on the Korean Peninsula
Venue: International Security
Year: 2021

In response to North Korea's nuclear weapons program, South Korea is quietly pursuing an independent conventional counterforce and countervalue strategy. This strategy is unique. Few, if any, nonnuclear states have sought to rely on advanced conventional capabilities to deter a nuclear armed adversary. Why is South Korea pursuing a conventional counterforce and countervalue strategy, and what could its impact be on strategic stability on the Korean Peninsula? South Korea's approach should be understood as both a short and long term hedge against U.S. abandonment. Its deterrent effect, no matter how uncertain, acts as a short term stopgap if the United States abandons South Korea. Over the long term, capabilities such as advanced ballistic and cruise missiles bolster South Korea's nuclear latency. At the same time, we highlight that the strategy poses numerous technological and operational difficulties and has negative implications for arms race and crisis stability. Given South Korea's approach and North Korea's response, disarmament efforts focused purely on the bilateral U.S. North Korea relationship will not succeed. Rather, any agreement will now need to address the growing gap in the conventional balance of forces on the Korean Peninsula.
China's public diplomacy towards Africa
Year: 2018

This thesis analyzes China's public diplomacy in the field of Sino Africa relations, arguing that China has adopted public diplomacy with soft power as a vital component of its foreign policy on the continent from the early 2000s onward. The necessity of public diplomacy in China's foreign policy was driven by the objective of developing close economic ties with African countries even as Beijing faced manifold issues in its relations. To comprehend the link between China's public diplomacy and Sino Africa economic ties, the research adopts an International Relations approach of neoliberal institutionalism, examining the use of public diplomacy to manage the asymmetric relations between China and Africa, in which China wields economic dominance over Africa. With the rising importance of public diplomacy globally in the twenty first century, China has employed its public diplomacy to explain and justify its rising global influence, and to dispel negative publicity in the international society. While China has a government centered public diplomacy system, unlike that of the West, various actors (governmental, semi governmental, and non governmental actors) systematically engage in China's public diplomacy through diverse instruments such as foreign aid, media, institutions for exchanging culture, and language training to the populations of foreign countries. The Chinese government deploys its public diplomacy in African countries based on smart power, which combines soft power (culture) and hard power (China model and economic power) as most of China's public diplomacy is linked to aid projects, grants, and low interest loans for building closer economic relations with African countries. China's public diplomacy seeks to build a positive image of China that focuses on a mutual sense of solidarity to elicit connectedness and shared identity between China and partner countries, mutual development, and harmonious coexistence through diverse public diplomacy activities. Public diplomacy fills the gap between China and Africa in asymmetrical economic relations that give rise to issues of distrust and discontent towards China such as the exploitation of African wealth, and accusations of neocolonialism. By conducting fieldwork in Nigeria and South Africa, the research confirms that China's public diplomacy is integral to its foreign policy that focuses on China's economic development and securing its position on the global stage through African partnerships, bilateral and multilateral (FOCAC) It also discovered that Chinese public diplomacy not only promotes an amicable and friendly environment that promotes deepen relations for economic objectives, but also boosts China's claim to be a global great power in the new era, as President Xi Jinping has ordered.

Chemical reaction in peristaltic motion of MHD couple stress fluid in channel with Soret and Dufour effects
Year: 2018

This paper looks at the peristaltic motion of MHD couple stress fluid in an inclined asymmetric channel. Simultaneous effects of heat and mass transfer are considered. Soret and Dufour features lead to the coupled differential systems. Channel walls satisfy the convective conditions of heat and mass transfer. Exact solutions for the stream function and pressure gradient are derived. Temperature and concentration are obtained numerically. Graphical illustrations for axial velocity, temperature, concentration and streamline patterns are developed. Physical interpretation of obtained results has been presented. It can be seen that both Soret and Dufour numbers reduce the concentration field while reverse effect is seen towards temperature for both numbers. It is also observed that concentration reduces towards destructive chemical reaction and enhances for constructive chemical reaction. The heat transfer Biot number gives rise to fluid temperature. Further more the mass transfer Biot number decreases the concentration.
The clinical epidemiology of sickle cell anemia In Africa
Venue: American journal of hematology
Year: 2018

Sickle cell anemia (SCA) is the commonest severe monogenic disorders of humans. The disease has been highly characterized in high income countries but not in sub Saharan Africa where SCA is most prevalent. We conducted a retrospective cohort study of all children 0 13 years admitted from within a defined study area to Kilifi County Hospital in Kenya over a five year period. Children were genotyped for SCA retrospectively and incidence rates calculated with reference to population data. Overall, 576 of 18,873 (3.1% admissions had SCA of whom the majority (399; 69.3% were previously undiagnosed. The incidence of all cause hospital admission was 57.2/100 person years of observation (PYO; 95%CI 52.6 62.1) in children with SCA and 3.7/100 PYO (95%CI 3.7 3.8) in those without SCA (IRR 15.3; 95%CI 14.1 16.6) Rates were higher for the majority of syndromic diagnoses at all ages beyond the neonatal period, being especially high for severe anemia (hemoglobin <50 g/L; IRR 58.8; 95%CI 50.3 68.7) stroke (IRR 486; 95%CI 68.4 3,450) bacteremia (IRR 23.4; 95%CI 17.4 31.4) and for bone (IRR 607; 95%CI 284 1,300) and joint (IRR 80.9; 95%CI 18.1 362) infections. The use of an algorithm based on just five clinical features would have identified approximately half of all SCA cases among hospital admitted children with a number needed to test to identify each affected patient of only fourteen. Our study illustrates the clinical epidemiology of SCA in a malaria endemic environment without specific interventions. The targeted testing of hospital admitted children using the Kilifi Algorithm provides a pragmatic approach to early diagnosis in high prevalence countries where newborn screening is unavailable.

This paper analyzes the effects of medical emergency on agriculture exports and the corresponding tax revenues by smallholder farmers in Cote d'Ivoire. It uses two complementary datasets: the 2016 CGAP smallholder survey and the 2015 Cote d'Ivoire living standard survey. The paper finds that a medical emergency decreases the likelihood that a smallholder farmer cultivates cocoa by 3.9 percentage points, drives them into poverty, and decreases the productivity by 10.5 percentage points. The paper then estimates that medical emergencies can decline cocoa exports by $922 million and tax revenues by $135 million, which represents 0.2% of the Ivorian GDP in 2017.

ObjectiveTo determine the nucleated red blood cell(NRBC)counts of passive smoking pregnancy and to study the relationship between cotinine concentration and nucleated red blood cell counts.MethodsThe demography of neonate were recorded.Cord vein blood of neonates were collected in passive smoking group(n=53) and non smoking group(n=41) were detected for complete blood cell index,nucleated red blood cell counts and cotinine concentration.ResultsThe passive smoking neonates had lower birth weight than that of control group(P0.05) and higher nucleated red blood cell counts(P0.05).NRBC counts in cord vein blood were significantly higher than those of control group(P0.05).The concentration of cotinine in cord vein blood was positively related with passive smoking amount(r=0.04,P0.01),however,NRBC counts in cord vein blood was not related with passive smoking degree(P0.05).ConclusionPassive smoking in pregnant period could cause the increase of nucleated red blood cell counts and the increase degree is not related to passive smoking amount.
A systematic study of the surface structures and energetics of CH3NO2 surfaces by first principles calculations
Venue: Journal of Molecular Modeling
Year: 2019

AbstractDensity functional theory (DFT) has been employed within the generalized gradient approximation and Perdew Burke Ernzerhof functional (GGA PBE) to study the structural and electronic properties of nitromethane (NM) surface models. Different surfaces, including (100) (001) (101) (110) and (111) are considered in this work. The corresponding properties of bulk crystal for NM were also calculated to form a contrast to the slab models. Results with anisotropic characteristics of different surfaces have been observed in this study. There was an obviously great anisotropy in electronic parameters, especially the band gaps of different surfaces, indicating the anisotropic impact sensitivity along different directions of NM. The band gap value for (111) surface, 2.687 eV, was smaller than that of other surfaces, showing a higher impact sensitivity for NM. The estimated anisotropy has been revealed in surface energies for different surfaces.
A Two Stage RPSO ACS Based Protocol: A New Method for Sensor Network Clustering and Routing in Mobile Computing
Venue: IEEE Access
Year: 2019

In the field of mobile computing, after the placement of sensor nodes, energy efficiency of data transmission in the sensor network is becoming a critical issue as the sensor nodes are battery operated devices. Most of the proposed protocols implement clustering based methods in order to balance the energy consumption among the sensor nodes through data aggregation. In this paper, a new method named a two stage RPSO ACS based protocol is proposed to improve the energy efficiency and network operation quality in the data transmission process, prolonging the lifespan of the network. Firstly, in the process of cluster head (CH) selection, the resampling particle swarm optimization (RPSO) is introduced, which shows better precision and efficiency than particle swarm optimization (PSO) and genetic algorithm (GA) Secondly, after the selection of cluster head, instead of the single hop transmission from the cluster heads to base station (BS) which is used in many papers, we adopt multi hop transmission to save energy. The ant colony optimization (ACO) is used to select the relay nodes between the cluster heads and the base station for the purpose of minimizing the energy consumption in the transmission process. In addition, we determine the reasonable threshold based on the energy consumption curve of the transmission. In this way, the nodes within a radius of the threshold from BS communicate with BS directly to save energy. Experimental results show that the proposed methods achieve the goal of improving the energy efficiency and operation quality of the sensor network in comparison to traditional methods.
FDM Based 3D Printing of Polymer and Associated Composite: A Review on Mechanical Properties, Defects and Treatments
Venue: Polymers
Year: 2020

Fused deposition modelling (FDM) is one of the fastest growing additive manufacturing methods used in printing fibre reinforced composites (FRC) The performances of the resulting printed parts are limited compared to those by other manufacturing methods due to their inherent defects. Hence, the effort to develop treatment methods to overcome these drawbacks has accelerated during the past few years. The main focus of this study is to review the impact of those defects on the mechanical performance of FRC and therefore to discuss the available treatment methods to eliminate or minimize them in order to enhance the functional properties of the printed parts. As FRC is a combination of polymer matrix material and continuous or short reinforcing fibres, this review will thoroughly discuss both thermoplastic polymers and FRCs printed via FDM technology, including the effect of printing parameters such as layer thickness, infill pattern, raster angle and fibre orientation. The most common defects on printed parts, in particular, the void formation, surface roughness and poor bonding between fibre and matrix, are explored. An inclusive discussion on the effectiveness of chemical, laser, heat and ultrasound treatments to minimize these drawbacks is provided by this review.

ORB SLAM, IMU and Wheel Odometry Fusion for Indoor Mobile Robot Localization and Navigation
Year: 2020

In this paper, we propose a light weight multi sensor fusion method containing ORB SLAM, IMU and wheel odometry for localization and navigation of an indoor mobile robot in GPS denied environment. Known as an accepted generally visual simultaneous localization and mapping (SLAM) system, ORB SLAM based on feature matching computes real time camera pose. The Inertial Measurement Unit (IMU) measures the angular velocity of the robot by one of its gyroscopes. The wheel odometry provides linear motion velocity for the robot and records distance the robot has moved. Through leveraging both rotation characteristic of IMU and linear characteristic of wheel odometry, the rough localization estimation for the robot is obtained. During every navigation of the robot, the rough localization estimation provides relatively accurate mapping scale of the real world for ORB SLAM. And the mapping scale revises the monocular camera pose of ORB SLAM to obtain global robot pose estimation in the real world. In the experiment, the robot can locate itself with tolerable error and perform great navigation ability in a specific scene.

Year: 2014

Over time, changes have affected not only the attitude towards people employed in organizations and the knowledge and intellectual capital, but also social values and responsibility. The aim of the paper is to analyse and assess the aspects of knowledge management and corporate social responsibility and their development in different human resource management (HRM) models. While researching the issue of HRM impact on the organizational performance, the authors have analysed several HRM models that show the relationship between HRM practices, the factors influencing their choice, and the organizational outcomes. The models differ with the unitary approach, which believes that employees and employers share the same interests, or with the pluralistic approach, which admits that different groups may have different interests.
