Welfare Economics Among the Theoretical Propositions of Economic Schools
Authors: Ali Mohammed Dr. Maha Kareem
Published: May 2023

The study aimed at the intellectual and theoretical analysis of the concept of welfare economics and to stand on the theoretical and analytical views and standards on which economic schools, the ideology of social democracy and the theorists of welfare were based on what constitutes welfare and how to achieve it. As for the importance of the study, it is to stand on these theoretical theses of economic schools and their policy to achieve a welfare economy and to know the criteria that provide the ability to measure whether the economic proposals and theses that have been developed have worked to improve the welfare of society. The problem of the study is the difference in the theoretical proposals of the economic schools in their vision to reach the welfare economy and achieve social welfare, and the difference is not a descriptive difference, but it includes different methods in seeing and understanding human behavior, and the most important results of the study are the focus of most contemporary welfare economists on the fact that effective markets do not necessarily achieve the greatest social benefit. Markets are not capable of self-regulation but require the regulatory role of the state. That the mixed ideology is the path to prosperity and glorification, such as social democracy, which was based on a new reform policy and a humancentered boom in the existing institutions. It included specific and measurable goals, such as the fair distribution of income and wealth. Thus, social democracy was unique in reaching and achieving a welfare society through the role of the state and its effective policy, by managing and providing welfare services in a better way, and that this transformation is a measure commensurate with the process of deepening and strengthening democracy. The study presented the most important recommendations to reach to a welfare society, then, the corrective interventional role of the state must be supported along with the work of the market and the adoption of the ideology of social democracy. Governments and institutions in all countries of the world should adopt new ways of thinking and actively participate in creating systems that will achieve real progress towards a more prosperous and prosperous world.

A Novel Sliding Mode Fuzzy Control based on SVM for Electric Vehicles Propulsion System
Authors: Boumediène Allaoua , Abdellah Laoufi
Published: May 2023

This paper presents a new sliding mode fuzzy control (SMFC) scheme for torque control of induction motors of the electric vehicles propulsion system. The control principle is based on sliding mode fuzzy control combined with space vector modulation (SVM) technique. The sliding mode fuzzy control contributes to the robustness of induction motor wheel drives of the electric vehicle propulsion system, and the space vector modulation improves the torque, flux, and current steady-state performance by reducing the ripple. The Lyapunov direct method reinforced with fuzzy logic is used to ensure the reaching and sustaining of sliding mode and stability of the control system. The performance of the proposed system is compared with those of conventional sliding mode controller and classical PI controller. Finally, computer simulation results verify the validity of the proposed method and show that the proposed control scheme provides robust dynamic characteristics with low torque ripple.

Authors: Soontornpipit Pichitpong
Published: May 2023

This paper contains simulated and measured data for 402-405 MHz radio propagation path loss in the consultation room for the allocated Medical Implant Communication System (MICS) band. The propagation models have been developed based on the number of partitions, concrete walls and objects between the transmitter and receiver. Unfurnished and furnished rooms were studied for indoor path loss and room penetration loss in a narrow band measurement. The received signals were measured, and effects from the indoor environment were evaluated to determine accurate impacts on the communication system. The fading in path loss for unfurnished and furnished indoor models with different polarizations was also considered. The path loss from the proposed models was illustrated and compared with the free space model. In this paper, the indoor wave propagation at the 403.5 MHz band was studied with both simulations and measurements to provide information that may aid the development of futuristic indoor communication for biotelemetry systems.

Published: May 2023

Lithography is one of the key technologies for scaling down a size of integrated circuits thus increasing the performance of an electronic device. Currently, there are many lithographic techniques that are potentially  capable to produce a nanometer feature size but the continuing development for a commercial use is still limited by extremely high investment especially on exposure equipment and mask. This paper introduces an alternative patterning technique called Trimming lithography as one of the strong candidates for future lithography, for producing sub-resolution and subexposure wavelength features. The pattern size can be downscaled by carefully adjusting the trim distance that is much higher than an original design linewidth. It is shown that the photoresist (PR) feature size can be scaled down with the acceptable profile to approximately 0.18 m from the original 0.8 m mask pattern with the 0.5 m resolution of the exposure tool. However, the pattern density of the line/space pattern becomes lower than that of the typical lithography. Different pattern qualities between dense and isolated patterns are probably explained by a diffraction occurring during a transmission of light through the mask slit.

Authors: Damanik Gerson , Sirat Djamhari , Gunawan Dadang
Published: May 2023

Today, the use of communication system for public safety and regulation purposes is still narrowband based, that is communication that transmits low-speed voice and data services. Each government agency, such as the government of Jakarta (Pemda DKI), police, health department, re department, and the national disaster management agency, builds its own network independently. Therefore, it is difcult to coordinate the service between agencies if there is an emergency situation or disaster. Good communication system for public safety services will create conducive condition that will eventually create tranquility in the community. Jakarta, as the capital city of Indonesia, needs communication systems that create such condition. This paper determines the number of e-Node B for 700 MHz digital dividend network for Public Safety Communication services in Jakarta based on LTE technology. The services include voice, video, and data. In this study, it is assumed that determination of the required number of e-Node B is started from year 2012 to 2022 by considering the bit rate required by the public safety ocer. The assumption of ratio of public safety ocer in Jakarta is based on its population data. Radio network planning is based on coverage approach and capacity approach. The design of its coverage and capacity are analysed by using network dimensioning. Dimensioning coverage is conducted by calculating the link budget for dense urban, and urban areas. We use the 9955 RNP (Radio Network Planning) to calculate the link budget and predict the system's coverage. From the calculation, it is shown that e-Node B number required to cover the Jakarta area is 140. Dimensioning of capacity is based on the services bit rate required by the public safety ocer. The services are , voice, video, and data. Trac prole is based on the assumption in year 2012, 2015, and 2020. By the capacity calculation, it is shown that a total of 49 sites is required.

A Novel Modelling and Controlling of Distributed Power Flow Controller (DPFC) Base on PSO Algorithm
Authors: Ajami Ali , Soulat Behrouz , Safari Amin
Published: May 2023

This paper focuses mainly on the state modelling controlling of a new FACTS device named Distributed Power Flow Controller (DPFC). The paper also discusses the role and function of DPFC in power ﬂow controlling together with its economic evaluation. DPFC is one of the Distributed FACTS (D-FACTS) devices. Its function is similar to that of UPFC but instead of one series converters, several low power series converters are used in DPFC. Therefore, DPFC includes multiple series converters and one shunt converter without common dc link. This eventually enables the DPFC to fully control all power system parameters. It, also, increases the reliability of the device and reduces its cost simultaneously. In this study a novel current injection model of DPFC is presented. The suggested model is suitable for steady state and stability studies. To use the presented model, a proper control system is needed. In this paper the PSO algorithm is used for optimal designing of controller parameters. Application of DPFC in diﬀerent operating conditions and failure in series converters are simulated with Matlab/Simulink software .The presented control system enables the DPFC to control the active and reactive power ﬂow at the transmission line independently. In conclusion, the resented simulation results show the validity and eﬀectiveness of suggested modelling and control system of DPFC for power ﬂow controlling.
Protection System Adjustment for High Penetration of Distributed Generation
Authors: Saksornchai Titti , Eua-arporn Bundhit
Published: May 2023

Excessive number and capacity of Distributed Generation (DG) may cause problems to distribution systems. To maintain existing protection coordination, the system can generally allow DG to be connected at a limited capacity. In case of more DGs are to be connected, it is a challenging issue for distribution system engineers to conduct protection adjustment for which the system can allow increased level of DG penetration. This paper proposes three methods, concerning protection system adjustment, to allow high DG penetration, consisting of over-current protection resetting, directional recloser application, and fuse replacement with recloser. The rst method will help relieve the system constraint from existing pick-up current settings whereas the second one helps solve the problem of mis-operation of the mid-line recloser caused by DG back feed fault current. The nal method will be used to maintain fuse saving scheme. In this paper, the developed methods are simulated with a test system to illustrate their eectiveness on allowing higher penetration of DG to the system.

Authors: Bigdeli Mehdi , Firoozi Hormatollah
Published: May 2023

For many years, an increasing interest existed in application of transfer functions (TF) method as a measure for detection of winding mechanical faults in transformers. However, this paper aims to change the application of TF method in order to evaluation of drying quality of power transformers during manufacturing process. For this purpose, support vector machine (SVM) is used. The required data for training and testing of SVM are carried out on 50MVA 132KV/33KV power transformer when the active part is placed in the drying chamber. Three dierent features extracted from the measured TFs are then used as the inputs to SVM to give an estimate for required time in drying process. The accuracy of proposed method is compared with the existing work in this eld. This comparison shows the superior capabilities of this proposed method.

Design of an Implantable Antenna Feasibility Study for Continuous Glucose Monitoring
Authors: Soontornpipit Pichitpong
Published: May 2023

The objective of this research was to design a patch antenna for communication with medical implants in the 402-405 MHz Medical Implant Communications Services band (MICS). Imbedded antennas used for biomedical telemetry such as cardiac pacemakers have been previously demonstrated for use either as sensing elements or as components of a wireless communication system. Designing an implanted antenna as a sensor is rather less di cult since the resonant frequency is seen to shift by changes in dielectric properties of the surrounding implanted areas affected by glucose levels. Based on our previous work of tissue characterization, an analytical technique can be developed to negate this frequency shift due to the change of permittivity and conductivity, from which the glucose levels are determined. This paper presents an antenna design used for communication from the implant to an external receiver, regardless of human tissue characterization. Using the genetic algorithm (GA) and the finite difference time domain (FDTD) method, the antenna is designed to have minimal detuning due to changes in blood glucose level. In this study, single and stacked nonhomogenous body layer for better performance were determined.

In this study a linearized Heffron-Phillips model of a single machine power system installed with a static synchronous series compensator (SSSC) has been presented. The optimal selection of the parameters for the SSSC controller is converted to an optimization problem which is solved by recently developed cuckoo optimization algorithm (COA). COA, as a new evolutionary optimization algorithm, is used in multiple applications. This optimization algorithm has a strong ability to find the most optimistic results for dynamic stability improvement. The effectiveness of the proposed controller for damping low frequency oscillations (LFO)  is tested  to variations in system loading and  results compared with particle swarm optimization (PSO). The results analysis reveals that COA minimized multi objective cost function and improved dynamic stability, better than PSO. Also, performance of proposed COA controller in 10 times run is the same as in 1 time run. In addition, designed COA based SSSC damping controller has an excellent capability in damping low frequency oscillations and enhances rapidly and greatly the dynamic stability of the power systems.
Various Methods of Realization for Fractional-Order Elements
Authors: Krishna Battula Tirumala
Published: May 2023

Fractional-order circuits are finding applications in control systems, signal processing, and other allied fields. As a result, realizing fractional-order elements or fractance devices is an essential research topic. A unique fractance device is realized in this study using continued fraction expansion (CFE) and partial fraction expansion (PFE) formulas. Continued fraction expansion is used to calculate the rational approximation. For simulation, the fourth order rational approximation for fractional order, =-1/2, -1/3, -1/4 is used. All simulations are carried out with the help of the MATLAB and TINA software packages. The theoretical and simulation results are in agreement.
VA Loading Optimization of a Converter Using the Rao Algorithm for Maximum Utilization of the Unified Power Quality Conditioner
Authors: Gade Swati , Agrawal Rahul
Published: May 2023

In a modern power system, the unified power quality conditioner (UPQC) is considered to be the most effective device for mitigating power quality problems. The use of the dynamic voltage restorer (DVR) for active-reactive power-sharing reduces the loading on the UPQC in all operating conditions, leading to better system efficiency and reliability. The VA loading of the DVC can be controlled by maintaining a proper angle between load and source voltage. In this paper, Rao algorithms are proposed to determine the optimal VA loading of the UPQC using the variable phase angle control method. The primary objective of this study is to determine the optimum angle at which the VA loading of the UPQC is minimum without negotiating the compensation capabilities. To illustrate the effectiveness of the proposed methodology, the results are compared to those for JAYA optimization. This research work will help in the development of an efficient, instantaneous VA loading-based control approach for the UPQC.
Observer-Based Integral Sliding Mode Controller for a Two-Wheeled Inverted Pendulum

Published: May 2023

The modeling and control of a two-wheeled inverted pendulum (TWIP) is gaining much interest due to the various advancements in hardware and computing technologies. A TWIP system has many advantages and applications. However, it still faces many challenges such as positioning, disturbance rejection, parameter uncertainties, etc. In this paper, a control scheme based on modern control techniques is presented to overcome these issues. Furthermore, an observer-based robust integral sliding mode controller (ISMC) is proposed for the nonlinear TWIP system. Firstly, a robust integral sliding mode controller is designed to tackle short-term and long-term constant and time-varying disturbances as well as issues relating to parameter variation. Secondly, the reduced-order observer is designed to estimate immeasurable states, enabling simplified implementation. It is then applied to the nonlinear model of the TWIP system, and performance is observed under different transient conditions. A comparison with prevalent controllers in the literature is carried out. This comparison relates to graphical results, time domain specifications, and error performance indices, calculated for states. From this, a significant qualitative improvement can be observed with the proposed controller for all types of transients. In quantitative terms, zero steady-state error with disturbances and a five-fold improvement in settling time with parameter variations are observed. This paper also discusses the software Simulink realization for modeling and control of the TWIP system, which can be valuable for novices working in this area.
The sinking of the Oxford-Cambridge Arc: strategic planning in England at a nadir?
Authors: Valler David , Allmendinger Phil , Nelles Jen
Published: May 2023

There is a clear consensus amongst both academic commentators and the professional community that current arrangements for strategic planning in England are inadequate. The withdrawal of central government from leadership of the proposed ‘Oxford-Cambridge Arc’ in early 2022 marks a particular nadir, not least given the ambitions for the planning of the area set out only a year earlier. This article offers a conjunctural reading of the failure of the proposed Arc spatial framework, emphasising that not only was the process of planning the Arc itself problematical, but it also faced wider governmental and political headwinds which fuelled public opposition to the scheme, reduced central government commitment and redirected political priorities elsewhere. In this context the prospects for the future of strategic planning in England appear rather bleak.

KASH TRAINING MODELS: INCREASING LEVELS OF COMMITMENT AND ORGANIZATIONAL EFFECTIVENESS
Authors: Cabrera-Moya Diego Rafael Roberto , Vasudevan Hemaloshinee , Prieto-Rodriguez Germán
Published: May 2023

The purpose of this article is to propose a strategic evaluation framework based on KASH training models, applicable in the first instance to SMEs in the clothing manufacturing sector in Bogota (Colombia), which in turn allows the possibility of developing new methodologies based on this proposal to be replicated in organisations from different sectors, as well as taking advantage of the possibility of increasing levels of commitment and motivation. The population of formal employees in this sector in 2021 was 626,350, and therefore the sample will be 384 employees. This framework is proposed as a set of postulates or tentative hypotheses in such a way that its approach becomes the support of a general framework and its subsequent verification through the analysis of the information collected in the sample about the perception of the relationship of the 4 KASH dimensions with commitment and organisational effectiveness. The main conclusion of this article proposes that each employer has differential expectations regarding the knowledge, skills, attitudes, and habits of employees and that, for this reason, the standard recruitment profiles must be complemented with adjusted training models that allow the use of the interaction of these 4 dimensions for the improvement of the levels of organisational effectiveness and commitment of the employees with the objectives of the firm.

We perform an in-depth analysis of the recently validated TOI-3884 system, an M4-dwarf star with a transiting super-Neptune. Using high-precision light curves obtained with the 3.5 m Apache Point Observatory and radial velocity observations with the Habitable-zone Planet Finder, we derive a planetary mass of

and radius of 6.4 ± 0.2 R
⊕. We detect a distinct starspot crossing event occurring just after ingress and spanning half the transit for every transit. We determine this spot feature to be wavelength dependent with the amplitude and duration evolving slightly over time. Best-fit starspot models show that TOI-3884b possesses a misaligned (λ = 75° ± 10°) orbit that crosses a giant pole spot. This system presents a rare opportunity for studies into the nature of both a misaligned super-Neptune and spot evolution on an active mid-M dwarf.

Planet formation imprints signatures on the physical structures of disks. In this paper, we present high-resolution (∼50 mas, 8 au) Atacama Large Millimeter/submillimeter Array observations of 1.3 mm dust continuum and CO line emission toward the disk around the M3.5 star 2MASS J04124068+2438157. The dust disk consists of only two narrow rings at radial distances of 0.″47 and 0.″78 (∼70 and 116 au), with Gaussian σ widths of 5.6 and 8.5 au, respectively. The width of the outer ring is smaller than the estimated pressure scale height by ∼25%, suggesting dust trapping in a radial pressure bump. The dust disk size, set by the location of the outermost ring, is significantly larger (by 3σ) than other disks with similar millimeter luminosity, which can be explained by an early formation of local pressure bump to stop radial drift of millimeter dust grains. After considering the disk’s physical structure and accretion properties, we prefer planet–disk interaction over dead zone or photoevaporation models to explain the observed dust disk morphology. We carry out high-contrast imaging at the

L

band using Keck/NIRC2 to search for potential young planets, but do not identify any source above 5σ. Within the dust gap between the two rings, we reach a contrast level of ∼7 mag, constraining the possible planet below ∼2–4 M
Jup. Analyses of the gap/ring properties suggest that an approximately Saturn-mass planet at ∼90 au is likely responsible for the formation of the outer ring, which can potentially be revealed with JWST.
La place des industries créatives et culturelles dans les politiques publiques
Authors: Salvador Elisa , Benghozi Pierre-Jean
Published: May 2023

Ces dernières années, l’attention portée aux industries culturelles et créatives (ICC) s’est largement renouvelée. Celles-ci sont en effet devenues un point focal des recherches en économie et gestion du fait de leur poids dans la société ainsi que par leur caractère de laboratoire des modes de créativité et d’innovation. On peut néanmoins s’interroger pour savoir si cette attention portée aux ICC a émergé en raison de la dynamique interne propre au secteur ou si elle n’est pas plutôt le résultat d’un ciblage des politiques publiques mettant ce secteur particulièrement en avant. Comprendre l’origine de l’attention portée aujourd’hui aux ICC et celle de la génération des concepts associés est donc important particulièrement intéressant à la fois pour mieux appréhender les stratégies sectorielles et pour éclairer la structuration et la construction des thématiques de recherche associées. Dans cette perspective, cet article éclaire, à partir du contexte européen, la manière dont le concept d’ICC s’est progressivement imposé dans le champ institutionnel. L’analyse approfondie du contenu des différentes communications émises, au fil des ans, par la Commission européenne permet de mesurer le poids croissant qu’y ont pris des enjeux des ICC, la manière dont la signification et le sens de la notion ont été construits, la place qu’elle a prise dans les actions publiques au-delà de politiques culturelles établies de longue date.
