Effect of load level of corner columns on punching shear resistance of flat slabs
Authors: Gołdyn Michał , Urban Tadeusz
Published: October 2020

The problem related to the effect of the corner column load on the punching shear resistance of the slab was presented. Existing experimental studies on internal columns demonstrated that the column pressure could lead to an increase in the punching shear resistance. Because of different confinement conditions of corner column-slab connection joints, it is unclear if such an effect exists for corner columns. New experimental investigations were initiated to clarify this issue. They covered a total of three corner column-slab connection specimens – slabs with a thickness of 140 mm and a longitudinal reinforcement ratio ρl = 1.09% connected with columns of a cross-section of 200×200 mm. The only variable parameter was the column load equal to 500, 1000 and 1500 kN.

A reduction of the slab load-carrying capacity of about 9% due to a three-fold increase in the column load was noted. Therefore, the effect of the column load turned out to be opposite to that observed for most previous tests on internal column-slab connections, which could have a result of a limited capacity of the slab reinforcement due to additional tensile forces from the lateral expansion of joint concrete.

Comparison in the light of test results demonstrated, that EN 1992-1-1 procedure allowed for safe, yet conservative estimation of the punching shear resistance. An average ratio of experimental to theoretical load of 1.82 was obtained.

Objective. Study the influence of Bacillus subtilis and probiotic strains of lactic acid bacteriaon microbiological processes during fermentation of rolled moist corn grain. Methods. Microbiological, zootechnical. Results. The antifungal activity of probiotic strains of Bacillus subtilis ВРТB1 and Lactobacillus plantarum KT-L18/1 against micromycetes isolated from rolled moist corngrain was studied. It has been established that B. subtilis ВРТ-B1 actively inhibits the growth ofmoulds of the genera Mucor, Rhisopus and Penicillium and yeasts of the genera Sacharomyces andTorulopsis. L. plantarum KT-L18/1 shows weak antifungal activity, pronounced antagonism is onlyobserved against micromycetes of the genus Penicillium and yeast of the genus Torulopsis. Underexposure to B. subtilis ВРТ-B1 and L. plantarum KT-L18/1, was a 3-fold increase in the number oflactic acid bacteria on a day 70 compared to the same parameter in the baseline raw material; nobutyric acid bacteria, moulds and pathogenic microorganisms were detected. When air flow isavailable for prepared moist corn, the development of micromycetes is observed within 14 days inall variants, except for inoculation of raw materials with L. plantarum KT-L18/1. At the same time,the number of micromycetes increased 2.4 times in the moist corn without the introduction of preservatives, which increases the probability of accelerated aerobic spoilage of feed and the threat ofcontamination with mycotoxins. Feed acidity both on a day 70 of preservation and on a day 14 fromthe beginning of air access in variants with the introduction of probiotic strains of B. subtilis ВРТB1 and L. plantarum KT-L18/1 and biopreservative Sil-All 4×4 was stably optimal within pH 4.0 to4.3. In a preserved rolled moist corn grain without introduction of preservative, pH of the feedincreased from 4.6 to 5.2, which is favourable for the active development of aerobic microflora.Conclusions. Making of rolled moist corn grain treated with B. subtilis ВРТ-B1 and L. plantarumKT-L18/1 ensures the establishment of optimal levels of feed acidity, prevents the intensive development of putrefactive microorganisms, micromycetes, which contributes to better aerobic stabilityof feed for 14 days after access of air compared with feed without the use of probiotic microorganisms; saturates the moist corn with probiotic microflora beneficial for animals.

Published: October 2020

Solid state drives (SSDs)have emerged as faster and more reliable data storages over the last few years. Their intrinsic characteristics prove them to be more efficient as compared to other traditional storage media such as the Hard Disk Drives (HDDs). Issues such as write amplification, however, degrade the performance and lifespan of an SSD. This issue is in turn handled by the Garbage Collection (GC) algorithms that are put in place to supply free blocks for serving the writes being made to the flash-based SSDs and thus reduce the need of extra unnecessary writes. The LRU/FIFO, Greedy, Windowed Greedy and D choices algorithms have been described to lower write amplification for incoming writes which are different in nature. The performance of the GC algorithms varies based on factors such as pre-defined hot/cold data separation, hotness of data, uniform/non-uniform nature of incoming writes, the GC window size and the number of pages in each block of the flash memory package. Finally, it can be seen that the number of write frontiers so used, can dictate the separation of hot/cold data and increase the performance of a GC algorithm.

Recently, the higher education domain has been on a quest for rapid social, technical, economic and political overhaul as a result of the post-industrial environment. The quest has led to major changes and evolution in higher education institutes of learning. These factors of evolution in higher education are globalization and internationalization. Globalization and internationalization are closely related but different. Globalization can be likened to the context of economic and academic trends that are tailored to meet 21st century realities while internationalization is the process of planning and implementing products and services so that they can be adaptable to specific context such as language and culture. This research seeks to understand the approaches towards globalization and internationalization of engineering education in Africa. findings from the study revealed that the practice of engineering education is not only domiciled to a particular country, region or continent. As a result of human development and civilization, it has become global and internationalized and there are various approaches to globalization and internationalization which were expatiated on in the study. This study therefore recommends that there is a need to focus more on provision of adequate facilities such as better internet service and other information and communication technologies to encourage the conduct and practice of engineering education and more impetus should be given to internationalization of engineering education in Africa as it has the capacity to help develop the region.

Android OS, which is the most prevalent operating system (OS), has enjoyed immense popularity for smart phones over the past few years. Seizing this opportunity, cybercrime will occur in the form of piracy and malware. Traditional detection does not suffice to combat newly created advanced malware. So, there is a need for smart malware detection systems to reduce malicious activities risk. Machine learning approaches have been showing promising results in classifying malware where most of the method are shallow learners like Random Forest (RF) in recent years. In this paper, we propose Deep-Droid as a deep learning framework, for detection Android malware. Hence, our Deep-Droid model is a deep learner that outperforms exiting cutting-edge machine learning approaches. All experiments performed on two datasets (Drebin-215 & Malgenome-215) to assess our Deep-Droid model. The results of experiments show the effectiveness and robustness of Deep-Droid. Our Deep-Droid model achieved accuracy over 98.5%.

Weaving is considered to be the most versatile means of manufacturing fabric. Due to versatility, process control is mandatory to ensure the quality of the woven fabric becomes a diverse task with a broader scope. With the advent of technology speed of weaving has been drastically increased due to which variation in warp tension becomes an inevitable fact for value-added technical products. Further, variation in warp tension results in different pick density which causes a shade variation due to different amounts of dye penetration along with the fabric. Maintain constant pick density throughout weaving is considered as the most important aspect. The pick density is greatly affected by the warp gaiting tension at which the fabric is woven and experiment results revealed that the warp gaiting tension is considerably changed when the beam is weaved down. Authors attempt to statistically analyze the quantitative relationship between the warp gaiting tension and the pick density. However, due to the high level of variability of warp gaiting tension along the warp with slightly scattered nature of experimental data, setting up a relationship with adequate accuracy is beyond achievable. Hence the warp gaiting tension is first grouped using a statistical technique and established the relationship for each group. The level of accuracy for each model is evaluated at 95% of the confidence interval and thereby determined the permissible tolerance in warp gaiting tension under which the required pick density could be still achieved.

Chilli (Capsicum annuum), one of the essential ingredients in Sri Lankan cuisine, is widely cultivated for producing dried chilli. The narrow conical-shaped chilli pods with wrinkled surface do not support much of the existing common mechanical feeding systems such as augers or bucket conveyorsin the chilli processing plants. Therefore, the objective of this study is to design and develop a robotic arm with a proper grabbing technique to feed chilli into the grinding mill. Furthermore, it is intended to install the developed robotic arm in an industrial level processing plant to test the feasibility of theindustrial application.The industrial robot designed in this study is primarily composed of three parts: the base, the arm and the wrist. These components connect with joints to form a unit. At the end of the wrist, an end-effector, which is a gripper for grasping chilli pods, is located.ATmega328 microcontroller, micro switches and DC motors were used to operate the robotic arm. The feeding rate is automatically controlled using a Hall Effect sensor. The robotic arm grabber was placed on top of the chilli containing trough (2.5m wide, 10.5m long, and 1.25m high) of an industrial level chilli processing plant.When operating, the grabber could grab 1.640±0.128 kg of chilli from the bulk in a single operation. The average time taken for one complete cycle of grabbing chilli, lifting the grabber, turning the arm on to the conveyer and releasing chilli on to the belt conveyor, varies from 20 s and 30 s depending on the height of chilli in the trough. The feeding rate varies from 440.6 kg/h and 218.66 kg/h when chilli is grabbed from the top and the bottom layers respectively. Therefore, this system can be recommended for maximum feeding rate of chilli up to 218.66 kg/h. Capacity can be increased by adding the same mechanism parallel or scaling up the existing system.

India is a worldwide agriculture business powerhouse. Future of agriculture-based products depends on the crop production. A mathematical model might be characterized as a lot of equations that speak to the conduct of a framework. By using mathematical model in agriculture field, we can predict the production of crop in particular area. There are various factors affecting crops such as Rainfall, GHG Emissions, Temperature, Urbanization, climate, humidity etc. A mathematical model is a simplified representation of a real-world system. It forms the system using mathematical principles in the form of a condition or a set of conditions. Suppose we need to increase the crop production, at that time the mathematical model plays a major role and our work can be easier, more significant by using the mathematical model. Through the mathematical model we predict the crop production in upcoming years. .AI, ML, IOT play a major role to predict the future of agriculture, but without mathematical models it is not possible to predict crop production accurately. To solve the real-world agriculture problem, mathematical models play a major role for accurate results. Correlation Analysis, Multiple Regression analysis and fuzzy logic simulation standards have been utilized for building a grain production benefit depending model from crop production. Prediction of crop is beneficiary to the farmer to analyze the crop management. By using the present agriculture data set which is available on the government website, we can build a mathematical model.

Internet of Things (IoT) involves interconnecting smart devices for data collection and making intelligent decisions where, the usual devices become autonomous and smart. With the swift and fast paced developments in the area of smart cities, smart homes, and smart everything the Internet of Things (IoT) is creating an exceptional role that has scope for immense growth and potential. Its objective is the seamless integration of digital and physical worlds into one ecosystem that would lead to the latest intelligent era of the Internet. This state of the art technology can offer huge potential for businesses and offer opportunities for already existent areas like healthcare, energy etc. Yet due to insufficient security techniques IoT is not completely fool proof against security breaches and privacy issues. Since IoT is made up of devices that are resource- constrained and it has a complex environment, which makes enforcement of security measures even more complicated and tricky. This is where Blockchain’s (BC) “security by design” comes in; that is capable of tackling IoT’s foremost security requirements. Features like transparency, data encryption, auditability, operational resilience and immutability can help remove IoT’s architectural shortcomings. This paper focuses on this relationship and surveys the most relevant work in this area, for analyzing how blockchain is capable of solving the issues related to authorization and access control for IoT environments.

Published: October 2020

Background/Objective: The primary objective was to quantify the role of the number of Centers of Disease Control and Prevention (CDC) risk factors on in-hospital mortality. The secondary objective was to assess the associated hospital length of stay (LOS), intensive care unit (ICU) bed utilization, and ICU LOS with the number of CDC risk factors. Methods: A retrospective cohort study consisting of all hospitalizations with a confirmed COVID-19 diagnosis discharged between March 15, 2020 and April 30, 2020 was conducted. Data was obtained from 276 acute care hospitals across the United States. Cohorts were identified based upon the number of the CDC COVID-19 risk factors. Multivariable regression modeling was performed to assess outcomes and utilization. The odds ratio (OR) and incidence rate ratio (IRR) were reported. Results: Compared with patients with no CDC risk factors, patients with risk factors were significantly more likely to die during the hospitalization: One risk factor (OR 2.08, 95% CI, 1.60–2.70; P < 0.001), two risk factors (OR 2.63, 95% CI, 2.00–3.47; P < 0.001), and three or more risk factors (OR 3.49, 95% CI, 2.53–4.80; P < 0.001). The presence of CDC risk factors was associated with increased ICU utilization, longer ICU LOS, and longer hospital LOS compared to those with no risk factors. Patients with hypertension (OR 0.77, 95% CI, 0.70–0.86; P < 0.001) and those administered statins were less likely to die (OR 0.54, 95% CI, 0.49–0.60; P < 0.001). Conclusions: Quantifying the role of CDC risk factors upon admission may improve risk stratification and identification of patients who may require closer monitoring and more intensive treatment.
MIMICRY AND QUEST FOR IDENTITY: A STUDY OF ARVIND ADIGA’S THE WHITE TIGER
Authors: Subham Ghosh
Published: October 2020

In The White Tiger Arvind Adiga has portrayed a picture of India just after independence. Balram Halwai is the central character and this novel shows the struggle of Balram to make himself free from the “darkness”, establishing as a successful entrepreneur and thereby making his Identity. Mimicry of the colonizers is a very common thing in a colonized nation but this paper, through the examples of the characters in the novel, will show how the subjects of a colonized nation continue to imitate others even after the colonial rulers are gone and how through this imitation they constantly recreate their identity and seeks to find an establishment.
KEY WORDS: mimicry, identity, postcolonialism, Arvind Adiga

Hard Dead Zone and Friction Modeling and Identification of a Permanent Magnet DC Motor Non-Linear Model
Authors: Pérez-Gómez C. A. , Liceaga-Castro J. U. , Siller-Alcalá I. I.
Published: October 2020

The identification of a permanent magnet DC motor model including non-linearities dead zone, Coulomb friction, and viscous friction, is presented. The dead zone considered here is the so call "hard" dead zone, whereas the friction force is modeled in two different ways: first, considering the value of viscous coefficient friction as a constant and second, approximating viscous coefficient by a polynomial depending on motors rotor velocity. The polynomial representation of the viscous friction value allows it to be adjusted automatically as a function of the speed of the system, as occurs in real systems. Therefore, a model capable of better representing the real motor behavior along a wide range of operation is obtained. The non-linear model is validated and compared using real-time data obtained from Quanser's direct current motor control trainer system, using the numerical tool Matlab®/Simulink™

A saliency-specific and dimension-independent mechanism of distractor suppression
Authors: Gong Dongyu , Theeuwes Jan
Published: October 2020

During everyday tasks, salient distractors may capture our attention. Recently, it was shown that through implicit learning, capture by a salient distractor is reduced by suppressing the location where a distractor is likely to appear. In the current study, we presented distractors of different saliency levels at the same specific location, asking the question whether there is always one suppression level for a particular location or whether, for one location, suppression depends on the actual saliency of the distractor appearing at that location. In three experiments, we demonstrate a saliency-specific mechanism of distractor suppression, which can be flexibly modulated by the overall probability of encountering distractors of different saliency levels to optimize behavior in a specific environment. The results also suggest that this mechanism has dimension-independent aspects, given that the saliency-specific suppression pattern is unaffected when saliency signals of distractors are generated by different dimensions. It is argued that suppression is saliency-dependent, implying that suppression is modulated on a trial-by-trial basis contingent on the saliency of the actual distractor presented.
Alignment in spatial memory: Encoding of reference frames or of relations?
Authors: Schultheis Holger
Published: October 2020

A common assumption about spatial memory is that it is organized along one or more reference directions such that access to memory is easier along directions aligned with the reference direction(s). This assumption rests to no small part on frequently replicated alignment effects arising in judgment of relative direction. In this contribution, we report an experiment designed to investigate a possible alternative explanation of alignment effects. By contrasting performance in a judgment of relative direction task with performance in an ego perspective taking task, we tested to what extent alignment effects arise from encoding of relations in addition to or instead of from organization along reference directions. Experimental results suggest little if any contribution of relation encoding on alignment effects, thus lending further support to the assumption of reference directions in spatial memory. Data from both tasks yielded the same alignment effects and provided evidence for a single direction being encoded in memory. Moreover, our results shed new light on and raise questions concerning differential sensorimotor and cognitive influence on spatial memory use. While both influence memory use, systematic bias seems to arise solely from reference directions, along which memory is organized.

High-resolution Chromospheric Observations of a Solar Minifilament: Formation and Destabilization
Authors: Chen Hechao , Hong Junchao , Yang Bo , Xu Zhe , Yang Jiayan
Published: October 2020

Using H
α
line core and off-band imaging data from the New Vacuum Solar Telescope in China, we present a high-resolution observation on the entire life cycle of a solar minifilament from its birth to its final eruption. We find that the minifilament originates from a series of cascade-like reconfigurations of chromospheric fine structures. During which, owing to strong photospheric shearing and converging flows near its polarity inversion line, basic short chromospheric fibrils first slowly coalesce to elongated dark threads, and then further create a longer filament channel in a “head-to-tail” linkage scenario. In this course, obvious magnetic flux cancelation simultaneously proceeds below it, and further facilitates its destabilization. In its onset phase, clear clues indicate that the minifilament first starts to rise without brightening signals; instead, after a slow-to-fast acceleration, obvious runaway reconnection soon takes over its final jet-like eruption. Besides, off-band observations further reveal that the formed minifilament has a possible flux-rope configuration, and chromospheric upflows that detected in its early forming phase persistently supplies cool plasma into its channel. This observation is consistent with earlier observations and supports the view that both miniature and large-scale filaments may share analogous formation and destabilization mechanisms.
