Flexible Operation of Grid-Interactive Converters under Unbalanced Grid Conditions

The grid codes of power systems with high penetration of renewable sources impose stringent requirements on the operation of Distributed Renewable Energy Sources (DRES) under the unbalanced grid faults. A generalized power control strategy based on the symmetrical components is used in this paper to control the power delivery under unbalanced grid faults. The aim of this paper is to develop a reference current selection module for the current controller of grid-side converters, which would be adaptable to the grid requirements. The proposed joint strategies help the DRES to benefit from the linear controllability. The performance of the flexible control strategy and the joint strategies are evaluated, considering the power quality indices.
Bioactive Nanofibres for Wound Healing Applications

Electrospun nanofibres have become an exciting area in textile product development, due to their unique properties such as high surface area and porosity. Indeed, many studies on nanofibres have demonstrated their feasibility in various applications. For example, nanofibre scaffolds were shown to be promoters for tissue cell adhesion and encapsulators for drugs. In the past decade, numerous studies revealed the areas in which nanofibres can be useful, and capability for scaling-up nanofibre production, which established a starting step in the development of a new generation of textile products. However, many challenges faced today are complicated in nature and require a multidimensional approach to solve, necessitating multifunctional products. This review explored recent efforts in developing a new class of active textiles for wound care. The wound care sector is one of the most advanced in the medical industry, with a massive global demand from patients suffering from wounds, burns, and diseases such as diabetes. Ensuring satisfactory wound healing is often difficult due to the dynamic nature of the skin, requiring fulfilment of multiple objectives at different stages of the healing process. We demonstrated that by controlling how wound dressing release therapeutic agents, its mechanical responses to the wound and in aqueous environment, a wound dressing that can interact with different wounds can be developed.
Polymorphics SSR Markers of Chilli Parental and Breeding Lines in Chilli Resistance to Pepper Yellow Leaf Curl Virus (PYLCV)

Aksesi cabai IPBC12 telah diketahui memiliki gen ketahanan dominan terhadap PYLCV dan dapat dimanfaatkan sebagi donor gen untuk perakitan varietas cabai tahan PYLCV. PYLCV merupakan salah satu virus patogen penting pada pertanaman cabai di Indonesia. Identifikasi marka SSR polimorfik pada populasi persilangan antara IPBC12 dan varietas Yuni dilakukan untuk mendapatkan marka yang dapat digunakan untuk seleksi progeni hasil persilangan dan terpaut dengan sifat ketahanan terhadap PYLCV. Sebanyak 20 marka SSR dianalisis polimorfismenya pada dua tetua persilangan, kemudian marka yang polimorfik diuji pada galur generasi F1 dan F2. Hasil penelitian menunjukkan ada empat marka polimorfik pada kedua tetua persilangan, tetapi ketika diuji pada galur-galur keturunannya hanya 3 marka (CaBR61, CaBR64, dan CaBR98) yang polimorfik. Berdasarkan analisis marka, 14 galur F1 terkonfirmasi hasil persilangan antar aksesi IPBC12 dan varietas Yuni. Marka yang secara konsisten mendeteksi penurunan alel dari kedua tetua pada progeni F1 adalah CaBR61. Marka tersebut berpotensi sebagai marka seleksi galur-galur hasil persilangan pada tanaman cabai. Analisis molekuler pada galur-galur F2 tidak mendapatkan keterpautan antara marka dengan sifat ketahanan. Perlu analisis lebih lanjut menggunakan jumlah marka yang mencukupi dan tersebar merata dalam genom cabai untuk memetakan gen ketahanan terhadap PYLCV pada populasi persilangan antara aksesi IPBC12 dan varietas Yuni. Kata kunci: aksesi IPBC12, Capsicum annuum, seleksi berpandu marka, varietas Yuni
‘A New Career’: nostalgia, mortality, and David Bowie’s ‘I Can’t Give Everything Away’

ABSTRACT David Bowie’s swansong album Blackstar occupies a unique position in its proximity to the artist’s death: just two days. It thus provides an opportunity to examine how music, nostalgia, and mortality interact. Combining study into the links between music and nostalgia and analysis of use of quotation, I propose a reading of a ‘dual effect’ in which the track ‘I Can’t Give Everything Away’ explores themes of nostalgia and mortality whilst encouraging nostalgic feeling in its audiences. The article contributes to an understanding of how a musician’s death can alter audience interaction with their music, and how music itself can reflect mortality.
A Hybrid Fault-Tolerant Scheme for Flight Control Applications*

In this paper we present a new Hy- brid Failure Detection and Identification (FDI) and Adaptive Reconfigurable Control (ARC) scheme for achieving the desired flight performance in the pres- ence of multiple control effector failures that oc- cur short time apart. The failures include lock-in- place and hard-over. The problem of stable control reconfiguration in the presence of such failures is solved using a scheme employing multiple adaptive FDI observers and controllers and a suitably chosen decision-making mechanism. The scheme is shown to guarantee the detection and identification of a failed effector. Due to a convenient structure of the overall system, the observers can be modified on-line to reflect the new operating regime imme- diately following the failure. This enables fast FDI and effective ARC in the case of subsequent fail- ures. The stability of the overall FDI-ARC system is demonstrated using the Lyapunov method, while the approach is illustrated through numerical sim- ulations of the F-18 aircraft during carrier landing.

Ein Kennfeldverfahreri zur Auswertung der Signale von Dreifach-Hitzdrahtsonden / Calibration field technique to evaluate the signals of triple hot-wire probes

Es wird eine Methode zur Messung des zeitabhängigen Geschwindigkeitsvektors turbulenter Strömungen mit einer Dreifach-Hitzdrahtsonde entwickelt. Die Abhängigkeit der Anemometerspannung von Betrag und Richtung der Anströmung wird durch ein Empfindlichkeitskennfeld beschrieben. Dadurch wird die insbesondere bei Subminiatursonden ungenaue Beschreibung dieses Zusammenhangs durch die üblichen algebraischen Näherungsformeln, wie z.B. das ,Cosinus-Gesetz', vermieden.
SWOT Analysis of the Implementation of Work from Home Policies from the Point of View of Employees and Leaders at Budi Luhur University

In early 2020, the global Covid-19 pandemic hit the globe. The pandemic has spread to 212 countries as of early May 2020, including Indonesia. One way to reduce the spread of covid-19 is for the Indonesian government to establish a policy of working, learning and worshipping from home since the beginning of 2020. The impact of the policy for companies, the industrial world, government agencies and educational institutions is the application of the concept of working from home or Work from home. One of the private educational institutions, Budi Luhur University, with more than 500 employees, has implemented a Work from home policy since the end of February 2020. All employees, lecturers, and education personnel are still required to be productive in carrying out their respective duties and responsibilities. This study analyzed the advantages, disadvantages, opportunities and challenges of implementing work from home policies from the perspective of employees and leaders at Budi Luhur University. This analysis is done using SWOT methods and quantitative research methods. This research hopes that it can be used as a basis for decision making or policy for the leadership of Budi Luhur University related to the pattern of working from home or Work from home.
Dynamic vehicle model for handling performance using experimental data

An analytical vehicle model is essential for the development of vehicle design and performance. Various vehicle models have different complexities, assumptions and limitations depending on the type of vehicle analysis. An accurate full vehicle model is essential in representing the behaviour of the vehicle in order to estimate vehicle dynamic system performance such as ride comfort and handling. An experimental vehicle model is developed in this article, which employs experimental kinematic and compliance data measured between the wheel and chassis. From these data, a vehicle model, which includes dynamic effects due to vehicle geometry changes, has been developed. The experimental vehicle model was validated using an instrumented experimental vehicle and data such as a step change steering input. This article shows a process to develop and validate an experimental vehicle model to enhance the accuracy of handling performance, which comes from precise suspension model measured by experimental data of a vehicle. The experimental force data obtained from a suspension parameter measuring device are employed for a precise modelling of the steering and handling response. The steering system is modelled by a lumped model, with stiffness coefficients defined and identified by comparing steering stiffness obtained by the measured data. The outputs, specifically the yaw rate and lateral acceleration of the vehicle, are verified by experimental results.
Fingerprint Identification System Using Half Smoothing Filters

Fingerprints have been significantly utilized for enormous security systems for their high-level accuracy. They even have been used effectively in smartphone devices for payment in addition to the security purpose. In this paper we propose a new finger print recognition method based on ridge and valley features in finger print images. These features extracted by rotating Gaussian semi _filters. The novelty of this finger print approach based on the mixing of directional filters and differences of Gaussian filter ideas. We obtain a new ridge/valley detector enabling very precise detection of ridge/valley points. This method conducted on different fingerprints database images, the proposed method achieves recognition accuracy rate of more than 99% for three fingerprint image datasets ATVS, LivDet2009, and LivDet2011.
System Dynamics and Mathematical Method Application for the Strategic Foresight

In a rapidly changing environment, it becomes extremely important to anticipate future changes and developments. A key element of strategic action and policy-making is now to recognise the possibility of alternative futures, and to implement strategy that makes the best alternative possible. The policy making in this era also needs to be based on systematically gathered information with the active participation of all the stakeholders. All this refers to active planning method named strategic foresight. However, environment makes the business run very sophisticated, so forecasting with strategic foresight method still brings uncertainty about selection of the optimal scenario. That is why dynamic and multi-causal systems are typical attributes to describe the multi version storylines of the future performance and to set variables trends. To decrease a risk of a wrong scenario selection we employ methods of mathematics for fuzzy systems. In the paper the case study will be done. On the basis of the business example, system dynamics model will be simulated. The elementary computation will be prepared for the next step of analysis. Finally, authors use to selection procedure. The expected result is to find 3 scenarios respectively to applied criterion.The aim of this study is to present the way of application dynamic and mathematical tools into strategic foresight work. Foresight analysts often have problems with the right choice. To avoid these troubles it is worth to involve tools which give well solution to strategic planning problem.
Compensation effect of digestate of biogas factory in case of some macro elements deficiency

The aim of the modern agriculture is the sustainable development. It helps to keep the good environment for the next generations. One of the most important expectations regarding sustainable agriculture is the minimization of the use of industrial chemicals. By using by-products, we are able to decrease amounts of chemical fertilizers. One of these by-products is the digestate, also as known as digestate of biogas factory. This fluid contains several essential elements, for example N, K, S, Ca and Mg etc. and we can use it for nutrient supply in the crop production. The goal of the experiment was that we examined the effect of the fluid by-product of some macro elements (Ca, Mg, P, S and K) deficient maize plants. The fluid by-products were originated from a biogas factory located in Biharnagybajom. Maize (Zea mays L. cv. DKC 5170) seedlings were used in the experiments. We made hydroponics experiment in growth chamber, where the circumstances were controlled. We added 50 ml dm digestate to the nutrient solution. At the end of the experiment (on the 21 day) the quantity of photosynthetic pigments (chlorophyl-a, chlorophylb and carotenoids) and the dry weight of shoots and roots were measured in the plants that were grown on nutrient solution. When we added the digestate to the nutrient deficiency nutrient solution, a more favorable effect was achieved on the measured parameters. Due to these results, we suggest the usage of the digestate of biogas factory in agriculture.
Analysis of the Folded Systolic Array Based MVDR Beamformer

Abstract – Adaptive beamformers are widely used in radar, sonar and communications applications. They increase the directivity of the sensor system to the target while supressing the interfering signals. The beamforming is accomplished by adjusting the weights of the sensors. Optimal weight extraction based on systolic structures have been the subject of various researches. Systolic algorithms are parallel and fully pipelined structures which improve the performance of the beamformer. This paper presents the analysis of the Minimum Variance Distortionless Response (MVDR) beamforming system based on a folded systolic structure. The folded structure of the systolic array reduces the die size of the hardware implementation while the systolic architecture improves the throughput ratio of the beamformer.
Human–machine force interaction design and control for the HIT load-carrying exoskeleton

The HIT load-carrying exoskeleton is designed for enhancing the operator’s load-carrying capability. Human walking has the characteristics of diversity and randomness. It requires that the sensing system of exoskeleton could detect and identify the random motion of human body. In this article, a human–machine force interaction designing architecture is proposed for HIT load-carrying exoskeleton. The human–machine interactive forces at the kinematic terminals (the back and feet) are detected for the human movement identification. Four basic body modalities during the movement process are proposed, which could be automatically identified by the sensing system. The kinematic models for the swing leg and supporting leg are established, respectively. A positional deviation feedback control method based on the interaction force detection is designed. The experiments show that the human–machine interaction force detection at the back and feet and the identification of different body modalities and movement intention are feasible. The interactive forces on the back are far less than the payload, indicating that the exoskeleton has good power-assisted effect.
Low Cost Satellite User Terminals: Lessons from The Wireless Industry

Satellite Communications systems are expected to play a significant role in the distribution of data, video and multi-media content as part of emerging global telecommunications infrastructure. This is, in part, due to many unique advantages satellite systems offer, including: global coverage, instantaneous access, and broadcast and multicasting capabi lities. Affordability of ground segment for satellite systems still remains an important barrier to growth of satellite networks. Many of the satellite systems are designed with unique ground system requirements thus hindering volume production and achievi ng inherent price/volume advantages. Yet, it is possible to reach a substantial price reduction by applying innovative design techniques, coupled with commercial wireless low-cost manufacturing technology, which have been successfully applied to consumer products such as cell phone handsets and WLAN (802.11b/g/a) access points and modems. This paper examines the trends in satellite and wireless systems and how they may support each other to provide complete communications solutions around the globe. Cost reduction of satellite terminals is discussed using the approaches that have been successful in the wireless industry.
Implementation of factitious force method for control of 5R manipulator with skid-steering platform REX

In the paper implementation of the factitious force concept for a controlling complex mobile manipulator has been presented. As the nonholonomic constraint only lack of longitudinal slippage of wheels has been chosen – in skid-steering platforms lateral slippage is necessary to change orientation of such a platform. From a control theory point of view such a system is dynamically underactuated. As a solution to a underactuation problem a method of factitious force has been proposed. This method assumes extension on the dynamics level, in the form of an additional control inputs u v , which values are equal to zero equivalently. For a mobile manipulator, consisting of platform REX and 5R robotic onboard arm, a cascaded control law has been proposed. A simulation study was conducted for a mathematical model of a considered object with real values of physical parameters, i.e. lengths, masses, inertia moments etc. obtained from the 3D model. Results obtained in simulations have shown a proper action of the control system and convergence of tracking errors, occurring in a platform and in joints of a manipulator, to zero.
Bistable memory and logic-gate devices fabricated by intercrossed stacking of graphene–ferroelectric hybrid ribbons

A ferroelectric-gated graphene field-effect transistor was fabricated by consecutively stacking two distinct graphene–ferroelectric hybrid ribbons at right angles. Two graphene layers play different roles. One graphene layer acts as a gate electrode and the other graphene layer acts as a channel between two electrodes, source and drain. Electric gating at the gate graphene modulates the resistance of the channel graphene. By means of ferroelectric polarisation, bistable resistance states of the channel graphene could be recorded, and the retention time of bistability was estimated to be 460 days by extrapolating of two resistance values in time–resistance relationships. Furthermore, the underlying concept to fabricate bistable memory device was extended to the methodology to realise a logic-gate device by stacking three distinct graphene–ferroelectric hybrid ribbons.
Experimental study on residual strength of concrete confined with corroded stirrups

Corrosion of steel bars is a serious issue compromising the reliability of reinforced concrete structures. Previous research has proven that confined concrete has increased confined strength, ductility, energy dissipation capacity, etc. However, existing confined concrete models cannot accurately predict the strength and stress–strain relationship of concrete confined with corroded stirrups. This paper presents an experimental study on the behavior of eight square columns confined with stirrups damaged by accelerated chloride corrosion. The weight loss of the stirrup ranges from 5% to 31.7%. The stress–strain curves of confined concrete are obtained from the concentric compression loading tests. Based on the well-established Mander model, modification factors are introduced to account for the effect of corrosion on the confined strength, confined strain, and descending branch of the curves. These modification factors predict the constitutive relationship of concrete confined with square stirrups as a func.
