The stiffness of soft robot manipulators generally embodies the manipulator's ability to satisfy the desired position and force commands. The goal of this study is to compare and investigate variable stiffness strategies in improving the distal tip stiffness of two-segment soft continuum manipulator which have in-built stiffness chamber constructed via granular jamming. The first step is to characterize the behaviour of the manipulator with the change in pressure to determine the Young's modulus. Then forces and their resultant length change relationship is established and based on the two characterization work, the stiffness matrix is obtained. The result shows that the stiffness matrix obtained is able to reject disturbances at the distal tip of the manipulator and the activation of the in- built stiffness chamber via granular jamming further enhance the stiffness and robustness of the manipulator, giving multiple strategies in improving tip distal stiffness.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122096240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process is aimed to create a PDMS based microchannel and pump chamber with sufficient cross-sectional width and height to enable the high-transport rate of fluidic sample. The process replaces the SU-8 based channel filler that cannot be removed by PDMS compatible chemicals. This technique includes 4 main steps. The initial process uses the SU-8 photoresist to create the pathway followed with the second photolithography using the AZ 4620 photoresist to fill up the channel. The next process is to pattern the PDMS mold close to the photoresist and form a chamber. The last process is to remove the photoresist in the channel using acetone, so that the channel will be formed properly. The coating properties and surface quality were analyzed using scanning electron microscopy (SEM). The results showed that the studied process method can form the channels and pump chamber without any leaking that ensures an easier, simpler and more advantageous process compared to conventional lithography process.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125654867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such robots perform several tasks that require gripping objects while varying their stiffness values to adapt to the characteristics of the objects. So far, the use of soft materials in these variable stiffness grippers is limited. Four-dimensional (4D) printing allows creating complex structures that change their shape over time. This technique relies on the use of smart materials that change their shapes based on external stimuli. Therefore, this paper presents the use of 4D printed variable stiffness polylactic acid (PLA) actuators to create a variable stiffness gripper. The proposed actuators are 4D printed using four patterns, including grid, honeycomb, triangular, and rectilinear patterns. Combinations of these patterns are used to create 12 designs, where each design consists of two different patterns in its top and bottom parts. This combination allows each actuator to have a unique variable stiffness profile based on the pattern and the temperature used to activate the PLA. This also allowed the actuators to achieve different bending angles ranging from 1°to 12°. Then, selected actuators are used to develop a variable stiffness gripper that includes four fingers, where each finger consists of two joints and three segments. The segments are made from actuators that achieve different bending angles. The results show that the developed gripper is able to perform gripping when stimulated by temperature, making it suitable for various robotics applications.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131868212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper evaluates morphological analysis and AC breakdown properties of polypropylene (PP) and PP/propylene-based elastomer (PBE) blends. Six samples were prepared by using the melt-mixing technique including neat PP and PP/PBE blends at different elastomer content. The morphology was evaluated by using scanning electron microscopy (SEM). AC breakdown test was conducted towards PP and PP/PBE blends based on standards set out in ASTM D149. The obtained results show PBE dispersed uniformly in the PP matrix. PP blend with minimum PBE content presents the highest AC breakdown strength. Meanwhile, the inclusion of PBE beyond 10 wt% in PP blends show comparable result with neat PP.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130661453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematical developments regarding generalized system form, system Gramians, Lyapunov equations and reduction mechanism for bilinear SOSSs for infinite and finite frequency intervals have been discussed. The formulation involves derivative pairs of each state and reduction techniques for such systems require retention of state pairs in a reduced order model to make reduction meaningful/useful. Retention of the state's structure has been achieved by partitioning the system Gramians into position and velocity portions. Balancing Gramians with different combinations yields different second-order balanced truncation techniques (SOBTs). The resulting SOBTs are tested on a bilinear system model for infinite and finite interval applications. Results certify for correct development as per claimed superiority of later proposed techniques in the limited intervals. The proposed developments can be considered for model order reduction of discrete-time bilinear second order structured system application especially over finite and infinite frequency intervals.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work provides inputs on the degradation effect caused by NBTI on the p-JLFinFET which will degrade the electrical parameters of the device. The simulation is done by constructing the p-JLFinFET device structure with a gate length of 15 nm by using Sentaurus TCAD tool, and then applying a stress voltage to the p-JLFinFET's gate terminal to observe the NBTI characteristics. The electrical behavior of the simulated p-JLFinFET was compared with the previous JLFinFET experimental work for device structure validation. Once the device structure is validated, negative stress voltage is applied to the gate terminal of the p-JLFinFET for 10,000 seconds. The electrical parameters before and after stress application were analyzed and compared. Results show under stress application of -1.8V for 10,000s and have been extrapolated up to 10 years by using the power law method, the threshold voltage $(mathrm{V}_{text{th}})$ increased by 15.7% from its initial value thus causing an increase in the power consumption and slower switching speed of the device.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130505563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WPT system can be categorized into three groups based on power transfer distances which are near-, medium-, and far-fields. Near-field is wireless power transfer within short distance while medium-field is the wireless power transfer with range more than short distance but not more than far field distance. In the near-field, contactless techniques such as inductive coupling and capacitive coupling are employed in WPT. In the medium-field WPT, a magnetic resonant coupling approach is employed. Electromagnetic radiation is used in the far-field WPT. Energy encryption is crucial in ensuring that electricity is delivered to the intended recipient. The energy encryption methods used in the WPT system are therefore reviewed in this study. A study of several techniques reveals that the distance, effectiveness, and quantity of receivers are the primary determinants of the most appropriate energy.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122643594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, each generator must operate to meet the needs of the population. Economic load management (ELD) aims to schedule economical generators in the power system to produce minimum operating costs. At large, each generators have different generation costs due to type of generators and different positions from the load center. Furthermore, generator output which is usually not at the optimum level with power demand will also result in increased generation cost. So, it is important to propose a most effective and cost-effective method in power generation. If the generator efficiency is not achieved, high power loss will occur. In this study, Mutated Flower Pollination Algorithm (MFPA) has been proposed as the ELD solution by determining the generation value for each generator unit to produce the minimum generation cost according to the power demand. MFPA method will be compared with the Evolutionary Programming (EP) method and the Flower Pollination Algorithm (FPA). IEEE 6-bus-3-generator power system was chosen as the test system and simulated using MATLAB. The results show that the MFPA show better performance than FPA and EP by producing total fuel cost as well as minimum amount of power loss in short iterations.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121422930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through quantifying the intensity of a space weather event, from its genesis at the Sun to its effect on the ionosphere, many physical parameters must be extracted from scientific data. Consequently, they are used for the quick conveyance of a streamlined but sufficient space situational awareness. Nevertheless, space weather-driven ionospheric phenomena can impact many consumers in the communication and navigation domains, which are not adequately served by the existing indices. Here we propose and discuss the advantage of the new ionospheric index, known as M index over the Malaysian region in terms of disturbed storm time (Dst) and Total Electron Content (TEC). We took a geomagnetic storm event on 1st and 2nd June 2013. It has been found that the storm started effects over this region with a time delay of approximately 21 hours. The suggested ionospheric disturbance index may overcome several shortcomings of previous ionospheric measurements and may be appropriate as a possible driver for an ionospheric space weather scale.","PeriodicalId":428103,"journal":{"name":"2022 IEEE 20th Student Conference on Research and Development (SCOReD)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125746961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The widespread usage of UAV have potential but also new challenges such as the constantly changing network topology, and vertical height variations that caused changes in their geometry. UAVs' energy efficiency, 3D deployment, and security have shown to be bottlenecks in various applications together with the satellite, aerial and terrestrial layers that constitute the vertical Heterogeneous Network (v-HetNet). Scholars have studied the different aspects of UAV's aerial network as an extension of the terrestrial network, but few have developed the management of the various layers together. In this paper, we review works on the v-HetNet as an important enabler of 6G mobile networks.
