LMI-based multiobjective integral sliding mode control for rotary inverted pendulum system under load variations

This paper presents a multiobjective integral sliding mode controller (ISMC) for a rotary inverted pendulum system under the influence of varying load. Firstly, the nonlinear system is approximated to facilitate the desired control design via extended linearization and deterministic approach. By using both of these techniques, the nonlinear system is formulated into a nonlinear state-space representation where the uncertainties are retained in the model. Next, the design objectives are formulated into linear matrix inequalities (LMI) which are then solved efficiently through convex optimization algorithms. With proper selection variables, numbers of the decision variables for LMIs are reduced. Hence, it will reduce the numerical burden and believes the calculated values more viable in practice. Finally, simulation works are conducted and comparison is made between the proposed controller, such as normal ISMC and LQR. The simulation results illustrate the effectiveness of the proposed controller and the performance is evaluated through integral of absolute-value error (IAE) performance index

Alpha-tocotrienol is the most abundant tocotrienol isomer circulated in plasma and lipoproteins after postprandial tocotrienol-rich vitamin E supplementation

<p>Abstract</p> <p>Background</p> <p>Tocotrienols (T3) and tocopherols (T), both members of the natural vitamin E family have unique biological functions in humans. T3 are detected in circulating human plasma and lipoproteins, although at concentrations significantly lower than α-tocopherol (α-T). T3, especially α-T3 is known to be neuropotective at nanomolar concentrations and this study evaluated the postprandial fate of T3 and α-T in plasma and lipoproteins.</p> <p>Methods</p> <p>Ten healthy volunteers (5 males and 5 females) were administered a single dose of vitamin E [526 mg palm tocotrienol-rich fraction (TRF) or 537 mg α-T] after 7-d pre-conditioning on a T3-free diet. Blood was sampled at baseline (fasted) and 2, 4, 5, 6, 8, and 24 h after supplementation. Concentrations of T and T3 isomers in plasma, triacylglycerol-rich particles (TRP), LDL, and HDL were measured at each postprandial interval.</p> <p>Results</p> <p>After TRF supplementation, plasma α-T3 and γ-T3 peaked at 5 h (α-T3: 4.74 ± 1.69 μM; γ-T3: 2.73 ± 1.27 μM). δ-T3 peaked earlier at 4 h (0.53 ± 0.25 μM). In contrast, α-T peaked at 6 h (30.13 ± 2.91 μM) and 8 h (37.80 ± 3.59 μM) following supplementation with TRF and α-T, respectively. α-T was the major vitamin E isomer detected in plasma, TRP, LDL, and HDL even after supplementation with TRF (composed of 70% T3). No T3 were detected during fasted states. T3 are detected postprandially only after TRF supplementation and concentrations were significantly lower than α-T.</p> <p>Conclusions</p> <p>Bio-discrimination between vitamin E isomers in humans reduces the rate of T3 absorption and affects their incorporation into lipoproteins. Although low absorption of T3 into circulation may impact some of their physiological functions in humans, T3 have biological functions well below concentration noted in this study.</p

Preliminary Groundwater Assessment using Electrical Method at Quaternary Deposits Area

Alternative water sources using groundwater has increasingly demand in recent years. In the past, proper and systematic study of groundwater potential was varies due to several constraints. Conventionally, tube well point was drilled based on subjective judgment of several parties which may lead to the uncertainties of the project success. Hence, this study performed an electrical method to investigate the groundwater potential at quaternary deposits area particularly using resistivity and induced polarization technique. Electrical method was performed using ABEM SAS4000 equipment based on pole dipole array and 2.5 m electrode spacing. Resistivity raw data was analyzed using RES2DINV software. It was found that groundwater was able to be detected based on resistivity and chargeability values which varied at 10 – 100 Ωm and 0 – 1 ms respectively. Moreover, suitable location of tube well was able to be proposed which located at 80 m from the first survey electrode in west direction. Verification of both electrical results with established references has shown some good agreement thus able to convince the result reliability. Hence, the establishment of electrical method in preliminary groundwater assessment was able to assist several parties in term groundwater prospective at study area which efficient in term of cost, time, data coverage and sustainability

PERAN KONSELOR DALAM PENANAMAN PENDIDIKAN ANTIKORUPSI BAGI SISWA SMPN 5 KEPANJEN

Abstract: Corruption comes from the Latin "corruputio" or "corruptus" meaning damage or corruption (Samidan, 2011). Meaning of the word corruption is corruption, literally, malice, depravity, dishonesty, can be bribed, immoral, deviations from the Holiness (Karsona, 2013). Corruption may be defined as a misappropriation or misuse of State money and private for personal benefit or others. The Act of corruption can also damage a country in terms of economy and education. Corruption in Indonesia is already very worrying, and needs to be eradicated altogether, during the handling of the corruption eradication more done in the form of repressive actions, namely the Act provides punishment by holding the corruptor. Other strategies in the fight against corruption, one of them with preventive action or prevention of the occurrence of corruption, this action which is considered the most effective way to prevent the occurrence of corruption, namely through education pathways. This type of research is a case study, Bungin (2003) describes research case study is a study that is comprehensive, intensive, detailed and insightful as well as more directed in an effort to elucidate the issues or phenomena the contemporary nature and immediacy. Anti-corruption education modules can be delivered through the role of the Counselor/teacher BK through granting information services by delivering anti-corruption education values for students of JUNIOR HIGH SCHOOL. Anti-corruption education could be developed back-related media provided against the students.&#x0D; Keywords: Anti-corruption Education, Counselors, Students</jats:p

Postprandial metabolic fate of tocotrienol-rich vitamin E differs significantly from that of -tocopherol

Background: The detection of tocotrienols in human plasma has proven elusive, and it is hypothesized that they are rapidly assimilated and redistributed in various mammalian tissues. Objective: The primary study objective was to evaluate the postprandial fate of tocotrienols and -tocopherol in human plasma and lipoproteins. Design: Seven healthy volunteers (4 males, 3 females) were administered a single dose of vitamin E [1011 mg palm tocotrienol-rich fraction (TRF) or 1074 mg -tocopherol] after a 7-d conditioning period with a tocotrienol-free diet. Blood was sampled at baseline (fasted) and 2, 4, 5, 6, 8, and 24 h after supplementation. Concentrations of tocopherol and tocotrienol isomers in plasma, triacylglycerol-rich particles (TRPs), LDLs, and HDLs were measured at each interval. Results: After intervention with TRF, plasma tocotrienols peaked at 4 h (4.79 \ub1 1.2 \ub5g/mL), whereas -tocopherol peaked at 6 h (13.46 \ub1 1.68 \ub5g/mL). Although tocotrienols were similarly detected in TRPs, LDLs, and HDLs, tocotrienol concentrations were significantly lower than -tocopherol concentrations. In comparison, plasma -tocopherol peaked at 8 h (24.3 \ub1 5.22 \ub5g/mL) during the -tocopherol treatment and emerged as the major vitamin E isomer detected in plasma and lipoproteins during both the TRF and the -tocopherol treatments. Conclusions: Tocotrienols are detected in postprandial plasma, albeit in significantly lower concentrations than is -tocopherol. This finding confirms previous observations that, in the fasted state, tocotrienols are not detected in plasma. Tocotrienol transport in lipoproteins appears to follow complex biochemically mediated pathways within the lipoprotein cascade

Hazardous waste landfill leachate treatment using an activated sludge-membrane system

This research was aimed to investigate the capability of a combined system of activated sludge and microfiltration processes with backflushing technique to reduce organic carbon and nitrogen compounds in hazardous landfill leachates. The experiments included acclimation, batch and continuous processes. The continuous process was conducted with a 24 hour HRT (Hydraulic Retention Time), and the SRT (Solid Retention Time) ranged from 16 to 36 days. The aeration basin volume was 5 L and the membrane filter used was a hollow fiber module made from polypropylene with pore size of 0.2 μm. The batch process (without membrane separation) achieved its steady state condition over a period of 33 days. The removal of COD, BOD5 and ammonia-N were 52.5%, 94.3% and 75.5%, respectively. The kinetic parameters obtained are as followed : the maximum specific growth rate constant (μm): 0.96/day and the saturation substrate constant (Ks): 16,445.32 mg/L. The high value of Ks indicated that the leachate was not easily biodegraded. The continuous process revealed that the system with SRT of 32 days was more stable than that of 16 and 24 days. The reduction of COD, BOD5 and ammonia-N were 31.3%; 66% and 98%, respectively. The stable flux was achieved around 5 L/m2.hour.</jats:p
