Published: May 2021

Due to the emergence of new technologies over the past decade, vehicle speed assistance systems in intelligent transportation systems have frequently been discussed. Up to now, a systematic literature review has not been presented to discover and evaluate the different vehicle speed assistance approaches for on‐road vehicles in intelligent transportation systems. To overcome this issue, this research identified peer‐reviewed articles published in the most well‐known libraries from 2011 to 2020. 79 primary studies were then projected and a systematic analysis of the selected literature was conducted. The findings show different driving goals, namely eco‐driving, safety, comfort, travel time improvement as well as the high‐level objectives addressed by vehicle speed assistance systems. The analytical discussions are provided to show different perspectives, properties and limitations of the existing solutions. This analysis allows to provide future challenges and directions in this field of research.
Design of a switchable microstrip bandstop filter with signal/dual stopbands
Authors: Tang Ching‐Wen , Fan Yang‐Hsin
Published: May 2021

A switchable bandstop filter is proposed herein. In order to achieve switchability between a single ultra‐wide stopband and dual wide stopbands, a complex process of coupling synthesis is not necessarily required. By setting two diodes at the input and output port separately, this bandstop filter can be switched between single and dual stopbands. An exemplary bandstop filter with central frequency at 2 GHz is fabricated on Rogers RO4003C, a substrate with a thickness of 0.813 mm and an area occupying 29.3 × 29.7 mm. Agreement between the theoretical and measured results can validate the proposed circuit.
A modified design method of pulse repetition frequency for synthetic aperture radar system based on the single point equivalent squint model
Authors: Liang Yujie , Liang Yi , Zhang Gang , Xing Mengdao
Published: May 2021

Pulse repetition frequency (PRF) is an essential parameter in synthetic aperture radar (SAR). However, a small PRF value will cause spectrum ambiguity and a large value will increase the computational complexity. In highly squinted SAR imaging with maneuvering platform, the traditional PRF design methods used are airborne and space borne. SAR systems perform with a low precision because of the complex geometric configuration and system deviations. In order to adapt to the maneuvering platform SAR system, a modified design method of PRF is proposed in this paper. First, the azimuth spectrum of echoes is analyzed by establishing the SAR geometry base on the single point equivalent squint (SPES) model. Subsequently, the calculation of azimuth bandwidth is transformed into an optimization problem, and the lower limit of PRF is obtained by the Golden Section Method. Besides, the criteria of spectrum unambiguity and time sequence constraints in PRF design is also discussed in detail. Simulation experiments demonstrate the feasibility and accuracy of the proposed method.

Authors: Liu Kaicheng , Guo Ying , Wang Dan , Li Dezhi , He Guixiong
Published: May 2021

Regional integrated energy system (RIES) can realize multi-energy conversion and complementation so as to improve energy efficiency, which also brings more security risks. The regional integrated energy system security region (RIESSR) is a security analysis method to describe the safe area for the operating points of RIES based on the N-1 guideline. As a controllable device, energy storage (ES) which is installed in the energy hub (EH) plays an important role in improving system security. Therefore, this paper establishes the model of practical security region of RIES integrating energy storage, and studies the impact of ES on total supply capability (TSC) and practical security boundary. Finally, a specific case is set to simulate and verify the model. By comparing the scenario with ES and the scenario without ES, it can be seen that the solution result of TSC increases and the security region extends across quadrant when the RIES is integrated with ES system. The capacity and location of the ES also impact on TSC and RIESSR.
A Distributionally Robust Power Dispatch Model for Active Distribution Network
Authors: Zhuang Huihua , Zhuang Huimin
Published: May 2021

The uncertainty of distribution network operation is increasing with the integration of large-scale renewable distributed generation (DG) units. To reduce the conservativeness of traditional robust optimization (RO) solutions, a data-driven robust optimal approach, which incorporates the superiority of both stochastic and robust approaches, is employed to solve the dispatch model in this paper. Firstly, a deterministic optimal dispatching model is established with the minimum total operation cost of distribution network; secondly, a two-stage distributed robust dispatching model is constructed based on the historical data of renewable-generators output available. The first stage of the model aims at finding optimal values under the basic prediction scenario. In the second stage, the uncertain probability distribution confidence sets with norm-1 and norm-∞ constraints are integrated to find the optimal solution under the worst probability distribution. The model is solved by column-and-constraint generation (CCG) algorithm. Numerical simulation on the IEEE 33-bus system has been performed. Comparisons with the traditional stochastic and robust approaches demonstrate the effectiveness of the proposal.

Mathematical Model of VOCs Emission in Three-layer Building Materials
Authors: Du Zhehua , Lin Xin
Published: May 2021

A simple mathematical model is proposed to account for emissions of Volatile Organic Compounds (VOCs) from three-layer building materials. The model considers both the diffusion within three layer building materials and the mass transfer resistance through the air boundary layer. A general solution method based on Laplace transform is presented. Compared to other models capable of accounting for emissions of VOCs from multi layer building materials, the present model is fully analytical instead of being numerical. The present model was validated by the experimental data from the specially designed test. The results indicated that there was a good agreement between the model predictions and the experimental data. It can also be seen from calculation that model ignoring the boundary layer resistance cannot fully reflect the real situation.

Authors: Chen Guangrong
Published: May 2021

The distribution characteristics of zooplankton in shallow urban lakes of Lingnan that in the tropics and subtropics were studied. The results showed that Brachionus, Trichocerea, and Lecane were dominant species of composition and abundance. The abundance of large Cladocera was low, which was affected by high water temperature, food restriction, and predation pressure of fish. Rotifera, small Cladocera, and Nauplius were the main zooplankton. Combined with the analysis of typical tropical shallow urban lakes, the dominant zooplankton tended to have a small individual population. It was expected to provide a reference for the ecological restoration of tropical shallow-water urban lakes.

Phase change materials have good peak-shaving and valley-filling effects, which are effective for improving the thermal environment of passive thermal storage buildings. In this paper, phase change materials were applied to a solar greenhouse in the plateau area, and the indoor temperature is measured and analyzed under different meteorological conditions. It was concluded that when phase change materials were applied in the central region of Yunnan, where the temperature difference between day and night was large, it had a significant improvement effect on the thermal environment inside the solar greenhouse. The average outdoor air temperature, the maximum outdoor temperature difference between day and night, and solar radiation were the main factors affecting the temperature in the greenhouse. By analyzing and evaluating the effect of using phase change materials in solar greenhouses under different outdoor climate conditions, the advantages and limitations of using phase change greenhouses in different areas of the plateau were discussed.
Rendering English pharmacological terms into Ukrainian: Translation and didactic dimensions
Authors: Chernovaty Leonid
Published: May 2021

The research into the dependence of translation techniques choice on the term structure in the source language on the material of rendering 603 English single-word terms and terminological collocations (related to pharmacodynamics and pharmacokinetics) into Ukrainian contributed to suggesting the following preliminary conclusions. The choice of translation techniques in rendering single-word terms depends, to a certain degree, on their structure. The share of the dictionary equivalents decreases with the increase in the term complexity, falling from 82% in the case of simple terms and prefixal derivatives to 58% concerning the suffixal, 34% – prefix-suffixal and 9% – compound lexemes. The transcoding share is minimal with prefixal and simple terms, steadily growing with suffixal, prefix-suffixal and compound lexemes. Dictionary equivalents complemented by transcoding may be enough to render simple terms, prefixal derivatives may additionally require contextual substitution or addition in the case of suffixal lexemes. The growth in the terminology complexity results in the expansion of the translation procedures ranges to four or even six techniques in rendering the prefix-suffixal terms. Adjectival, participial and verbal two-word collocations are mostly translated by calquing. The addition of a noun reduces its share, increasing the role of transformations. The correlation of translation techniques depends on the nature of the added element. If it is an adjective, the impact of calquing grows; the addition of a noun contributes to the expansion of transformations.

Analysis of mechanical behaviors of waterbomb thin-shell structures under quasi-static load
Authors: Zhao Lijuan , Shang Zuen , Zhang Tianyi , Liu Zhan , Han Liguo , Wang Chongwang
Published: May 2021

Waterbomb structures are origami-inspired deformable structural components used in new types of robots. They have a unique radially deployable ability that enables robots to better adapt to their environment. In this paper, we propose a series of new waterbomb structures with square, rectangle, and parallelogram base units. Through quasi-static axial and radial compression experiments and numerical simulations, we prove that the parallelogram waterbomb structure has a twist displacement mode along the axial direction. Compared with the square waterbomb structure, the proposed optimal design of the parallelogram waterbomb structure reduces the critical axial buckling load-to-weight ratio by 55.4% and increases the radial stiffness-to-weight ratio by 67.6%. The significant increase in the radial stiffness-to-weight ratio of the waterbomb structure and decrease in the critical axial buckling load-to-weight ratio make the proposed origami pattern attractive for practical robotics applications.

Published: May 2021

The research is focused on realizing a comparative analysis regarding the parameters of an active water-cooling solution for improving the efficiency of monocrystalline silicon photovoltaic (PV) panels. The efficiency of the photovoltaic panels is dependent on the climatic conditions, varying especially with the change of the intensity of the solar radiation and of the operating temperature. The cooling of the photovoltaic panels is a viable solution for both fixed and variable positions of the system. Numerical modelling was carried out on a photovoltaic panel integrated into the façade of a buildings. The water-cooling solution consist in using a water film heat exchanger attached on the backside of the PV panel. The parameters of the heat agent analysed were the temperature, velocity and width of the water film. The optimal water film heat exchanger solution was obtained for a thickness of 3 mm of water film, a velocity of 0.01 m/s and an operating temperature of 20 °C. In this case, the thermal power extracted by the film exchanger reaches values of 140.8 W, with an overall heat exchange coefficient of 48.6 W/m2.K. During the study, the global heat transfer coefficient and the raise off efficiency is determined for each case.
Removing ammonium from water intended for human consumption. A review of existing technologies
Authors: Radu G , Racoviteanu G
Published: May 2021

Ammonium is an inorganic compound present in water at pH<9. Ammonium has no toxic effects on human health, but its presence in water can indicate a water pollution. The presence of ammonium in groundwater source can be largely determined by the reducing conditions from the aquifer, while in surface water sources it is found only in polluted waters. In water supply systems, the presence of excess ammonium in raw water is not desirable because it can generate problems such as: unpleasant odors, microbial development in the water distribution system, reducing the efficiency of chlorine disinfection and increased chlorine consumption. Over time, several methods have been developed to reduce the concentration of ammonium from water, these being physical, chemical, biological or a combination of these methods. The article presents a review of the technologies currently used to reduce /oxidize ammonium from water. These mainly includes: ion exchange and adsorption, biological filtration, air stripping, breakpoint chlorination and reverse osmosis.

Published: May 2021

Wedge or tapered foundations of buildings, which have greater top cross-sections than bottom ones, are not often considered as a design option due to their shape. However, precast wedge foundations could be considered as “quick foundation systems” in case of light structures which should be rapidly installed. Similar to tapered piles, this foundation shape can offer besides the bottom base resistance, a good lateral contact between the inclined concrete faces and the surrounding soil. The paper presents the experimental results of two wedge foundation specimens subjected to axial compression tests conducted in accordance to actual standards. The results recorded on sites are presented under the form of pressure-settlement diagrams and are compared with similar values recorded for usual prismatic foundations. The study is completed by an environmental impact analysis made on the two systems along with potential benefits and loads, beyond the system boundary, at the foundations’ end-of-life.
Seismic insulation of the base for buildings with masonry structures
Authors: Abdulfattah Abdulfattah Zainulabdeen K. , Draghici Robert
Published: May 2021

The purpose of this application is to see whether or not it is cost-effective to insulate the base of ordinary houses, made of load-bearing masonry. Certainly, the isolation of the base is suitable for structures of high importance, as well as historical monuments, but the common man does not live in a structure of high importance. Is the solution cost-effective for the average person? To test this hypothesis, we proposed a low structure (GF + 1) of confined masonry, located in a seismic area (Bucharest, ag = 0.30g, Tc = 1.6 sec) urban. The example is a multifamily duplex home.

The proposed structure being low, its own vibration period is small enough to be located in the area of maximum dynamic amplification in the response spectrum. For the simplified analysis we analysed starting from the hypothesis of a seismic force represented by the equivalent lateral force, according to the provisions of P100-1/2013. The basic concept of base isolation, respectively the decoupling of the structure from the foundation ground, also implies the increase of the own period sufficiently so that the structure is no longer in the area of maximum dynamic amplification of the response spectrum.
The effects of thermal insulation on the interior noise level during the day. A case study of a 1960 block of flats located in downtown Bucharest
Authors: Toma V.V. , Antonie S. , Catalina T.
Published: May 2021

The issues related to the propagation of outside noise to the occupied spaces are more frequent, especially in urban areas where different types of noises are present (constructions, traffic, etc.). It is medically proven that noise has negative effects on health: anxiety, lower intellectual performances, stress, fatigue or higher blood pressure. With the national refurbishment program of old buildings the constructors are insulating and replace old wood frame windows with more energy efficient ones. Despite the clear benefits in terms of energy reduction there are still some questions about the sound insulation of the facades. If the windows replacement is done in a wrong way the situation can be aggravated as air and noise can overpass. In this paper using experimental measurements it is evaluated the impact of thermal refurbishment of an apartment on the acoustic comfort. The data showed that the windows represent the weak part of the facade and incorrect mounting severely affected the indoor sound pressure level.

Published: May 2021

Transport is a significant branch of the economy due to its contribution to the creation of gross domestic product. In order to ensure a reliable transport network that boosts trade and economic growth, prior to the construction of new national roads and motorways, it is necessary to ensure a proper technical condition of the road. Therefore, road network administrators have to attain a balance between the program of maintenance / repair / rehabilitation activities and the works that can be executed within the limits of the available funds so that the investment achieves the highest profitability and the road network either viable. There are currently a number of factors that influence the decision-making process in prioritizing maintenance work as well as allocating funds so that the investment achieves the highest return. Therefore, a multi-criteria decision-making approach is needed to ensure a balance between the program of maintenance / repair / rehabilitation activities and the works that can be executed within the limits of available funds. In the present paper, the authors proposes to develop a decision support model based on the principles of the GIS information systems, to help the road network administrators to take decisions that prioritize the maintenance works.

The land transportation network in Semarang City in the early 20thcentury
Authors: Utama N J , Atno
Published: May 2021

Semarang City is a fascinating city to be studied historically through various aspects, including transportation problems. This paper tries to examine the condition of the transportation network in Semarang at least in the first 30 years of the 20th century. The main problem in this paper is how the condition of the transportation network in Semarang and its impact on Semarang people in the early 20th century. So far, the concern about historical studies in Semarang regarding transportation has always been regarding the railway network centered in this city. However, the railway network is only connecting Semarang with other areas in Central Java and beyond. What about the transportation conditions in the city of Semarang itself?. Of course, the train is not the primary mode if we talk about transportation mode inside the city. In the land transportation network in the big cities in the Dutch East Indies at the end of the 19th century, the mode of transportation using animal power played a huge role. However, changes began to occur when modern transportation modes, such as bicycles, motorbikes, cars, and trams, entered the Dutch East Indies, including Semarang City, at the beginning of the 20th century. The significant impact that occurs is that this mode of transportation provides a new network pattern in transportation, especially the land transportation network in Semarang. This study uses the historical method, which consists of four stages: heuristics, source criticism, interpretation, and historiography. The results of this study indicate that there are complex dynamics in the development of land transportation in Semarang, besides that technology plays an essential role in this development.
