The notion of the sub-exact sequence is the generalization of exact sequence in algebra especially on a module. A module over a ring R is a generalization of the notion of vector space over a field F. Refers to a special vector space over field F when we have a complete inner product space, it is called a Hilbert space. A space is complete if every Cauchy sequence converges. Now, we introduce the sub-exact sequence on Hilbert space which can later be useful in statistics. This paper aims to investigate the properties of the sub-exact sequence and their relation to direct summand on Hilbert space. As the result, we get two properties of isometric isomorphism sub-exact sequence on Hilbert space.

People with complete spinal cord injury (SCI) present a rapid process of muscle fatigue under neuromuscular electrical stimulation (NMES) due to neuromuscular impairment. Different NMES patterns interfere with the fatigue process and joint amplitude. The aim of this study was to evaluate muscle reactions using joint knee joint fatigue protocol with four NMES patterns in people with complete SCI. Ten subjects with complete SCI received 4 stimulatory profiles, varying pulse duration and the modulating frequency (burst): P1 (100μs-50Hz);P2 (100μs-70Hz);P3 (200μs-50Hz);P4 (200μs-70Hz). Subjects were classified according to theirself angular response as upper median (UPmed) and lower median (LOWmed). UPmed had lower angular variation and attenuation in the fatigue process than LOWmed in P1 (session I, trial 1 p=0.06, trial 2 p=0.009, trial 3 p=0.029, session II, trial 1 p=0.015), P2 (session I, trial 3 p=0.024, trial 4 p=0.034), P3 (session I, trial 3 p=0.035), P4 without intergroup difference. The angular variation can be applied as a useful tool for muscular condition classification of complete SCI people. The best performance of UPmed has occured in P1 and the worst in P4. The LOWmed performance did not stand out in any protocol. Copyright © 2018 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved

Rice straw is one of the abundant lignocellulosic agricultural by-product in Indonesia. Rice straw has several characteristics that make it a potential raw material for bioenergy production such as ethanol. It contain high cellulose and hemicelluloses that can be hydrolyzed into fermentable sugars. This study aimed to hydrolyze rice straw cellulose and hemicellulose using xylanase, cellulose, and xylose isomerase enzymes. 2% H2SO4 was used in pretreatment before the rice straw hydrolyzed with consortium enzymes. Concentrations of rice straw substrate was made to 5%, 10%, 15%, and 20% (w/v) and also made 1:1, 1:2, and 1:3 volume ratio between substrate and enzymes. The results showed that the highest rate of bioethanol obtained from 10% (w/v) rice straw substrate and enzyme activity in consortium was 0.279 U/mL (xylanase), 0.329 U/mL (cellulase), and 0.024 U/mL (xylose isomerase). The hydrolyzate was fermented by Saccharomyces cerevisiae BJ1824 and produce 8.81x10−2 %(v/v) ethanol measured by Gas Chromatography (GC).

IOP Conference Series: Materials Science and engineering 2019年第1期508卷

作者： Kristianto Leksmono Suryo Putranto Doctoral Program Student Civil Engineering Department Tarumanegara University Postgraduate Program Lecturer Civil Engineering Department Tarumanegara University

According to the data of accidents occurred throughout the period from January 2014 to September 2018 on the Tangerang-Merak toll road, there were 3117 traffic accidents which were spread across 72.4 kilometers of the Tangerang-Merak toll road. From the total number of 3117 accidents, 214 traffic accidents or 7% have occurred centrally in 10 Toll Gate locations. The picture of this situation seems to require further in-depth evaluation on why the accident at the Toll Gate whose location is centrally located is quite high compared to the accidents occured along the toll road section where the location is scattered, while the vehicle speed at the location of the Toll Gate should be already in low speed before stopping to make a toll payment transaction.

With its origin in sociology, Social Network Analysis (SNA), quickly emerged and spread to other areas of research, including anthropology, biology, information science, organizational studies, political science, and computer science. Being it's objective the investigation of social structures through the use of networks and graph theory, Social Network Analysis is, nowadays, an important research area in several domains. Social Network Analysis cope with different problems namely network metrics, models, visualization and information spreading, each one with several approaches, methods and algorithms. One of the critical areas of Social Network Analysis involves the calculation of different centrality measures (i.e.: the most important vertices within a graph). Today, the challenge is how to do this fast and efficiently, as many increasingly larger datasets are available. Recently, the need to apply such centrality algorithms to non static networks (i.e.: networks that evolve over time) is also a new challenge. Incremental and dynamic versions of centrality measures are starting to emerge (betweenness, closeness, etc). Our contribution is the proposal of two incremental versions of the Laplacian Centrality measure, that can be applied not only to large graphs but also to, weighted or unweighted, dynamically changing networks. The experimental evaluation was performed with several tests in different types of evolving networks, incremental or fully dynamic. Results have shown that our incremental versions of the algorithm can calculate node centralities in large networks, faster and efficiently than the corresponding batch version in both incremental and full dynamic network setups.

Past air sampling detection (ASD) systems had no definitive positioning;most allocation of sampling points was based on experience. This research discovered that sampling points inside the electrical rooms were significantly affected by the ambient airflow, causing the detection system to have difficulties in fire detection. Fire dynamics simulator (FDS) was used to simulate very early smoke detection apparatus (VESDA) effectiveness within the protection area of an electrical room. Results showed that ASD sampling points in electrical rooms should be placed above high-voltage transformers and capacitors, while rearranging the high risk machines together to avoid long detection pipelines, which increases the transportation time of the gas, thus hindering early detection by the ASD system. Field tests using a smoke detector tester yielded transportation times of 33 s, which was in very good agreement with the simulated results of 35 s by ASPIRE, showing the accuracy of using software to simulate transportation times. Therefore, this research combined FDS with the transportation times of different pipeline designs to conduct performance assessment of VESDA. After appropriate rearrangement of machines, VESDA detection times dropped from 106.0-171.0 s during the original setup to 21.0-31.7 s, assuring the facility to have more time for emergency response. However, it was noticed that FDS software did not have the estimation tool for VESDA transportation times;therefore software such as ASPIRE should be used to calculate the gas transportation times inside the detection pipelines, and then compiled with FDS results to avoid underestimation of actuation times. © 2017 The Authors.

Journal of Physics: Conference Series 2020年第1期1500卷

作者： B Alfaresi Z Nawawi R F Malik K Anwar Electrical Engineering Universitas Muhammadiyah Palembang Indonesia Doctoral Program of Engineering Science Universitas Sriwijaya Indonesia Electrical Engineering Universitas Sriwijaya Indonesia Computer Science Department Universitas Sriwijaya Indonesia Center for Advanced Wireless Technologies (AdWiTech) Telkom University Indonesia

Next generation wireless technology require a wide frequency band. Current technology use a frequency of below 3 GHz which cannot provide a wide frequency band due to quite dense frequency utilization. The mm-Wave frequency guarantee to provide a wide band frequency band. The use of mm-Wave frequency will be influenced by climate factors. The characteristics of a place will cause a different channel model. Channel Model is useful for minimizes errors and maximizes information transmission or bitrate in communication model. The Channel Model will be represented as a PDP (Power Delay Profile). Channel model performance uses the Outage performance parameter in Shannon Theorem Implementation. Validation results using the CP-OFDM system with 5G BPSK. The parameters used for validation are FER and BER. In this paper, channel models will be analysed based on the characteristic of Palembang area as a reference channel model in Outer of Indonesia. Hopefully, it can be used as a reference for the development 5G wireless system.

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.

Off-site domestic wastewater management system in Banda Aceh, Indonesia: the problems and future solutions concept

引用

IOP Conference Series: Earth and Environmental Science 2021年第1期644卷

作者： J Harahap T Gunawan S Suparayogi M Widyastuti Department of Environmental Engineering Faculty of Science and Technology Islamic State University of Ar-Raniry Banda Aceh Indonesia Student of Doctoral Program in Environmental Science School of Postgraduate Universitas Gadjah Mada Indonesia Department of Cartography and Remote Sensing Faculty of Geography Universitas Gadjah Mada Indonesia Department of Environmental Geography Faculty of Geography Universitas Gadjah Mada Indonesia

Currently, Banda Aceh has been dealing with several problems related to pollution caused by domestic wastewater. According to previous studies, shallow groundwater and surface water in Banda Aceh have been contaminated by domestic wastewater produced by the community. The settlement scale off-site system with communal-WWTP operating in several villages has not function optimally in treating domestic wastewater. The problem also caused by service coverage which is still very small (only 2.12% of the total population). Therefore, it is require an acceleration of service improvement, by developing urban scale off-site system with centralized-WWTP and a wider pipe line network system. Moreover, further investigations are needed to develop the concept of planning as a preliminary design in the management of urban scale off-site system. This paper aims to develop a concept of domestic wastewater management using an urban scale off-site system that considers environmental characteristics in Banda Aceh as an alternative to mitigate the occurrence of water body pollution by domestic wastewater.
