THEORETICAL ELEMENTS OF ENERGY MODULAR LAYOUT OF AUTOMOBILE SYSTEM

The article presents a physical and mathematical model of the energy-modular configuration of a vehicle. A technique for modeling the motion of an automobile system with main connections based on the Lagrange equations is considered. This approach allows us to represent the model of the automotive system as a combination of two platforms, force factors and mechanical links, ensures their combination in one workflow. An equation has been drawn up and calculations have been carried out to change the kinetic energy for various modes of motion of the automobile system. The aim of the study is to improve the technology of moving the automotive system using a combination of two mobile platforms. The scientific and practical significance of the work lies in the fact that for the first time a technology has been proposed in which the energy of interaction of two platforms is used to move the automobile system. The research methodology was to establish a mathematical relationship between the generalized force and the dynamics of platform interaction, which is responsible for the movement of the automotive system. The result is the developed geometry of the interaction between platforms in the damping cycle of the interacting platforms. The value of the study, the results of the work carried out make it possible to contribute to the automotive industry. A model is proposed to reduce the energy to create vehicle motion.

The Simulation Model of Iron Sponge Plant Layout for the Defense Industry Based on Industry 4.0 Model

The Industry 4.0 is a change in the perspective of how to view an industry based on the resources owned, to operate according to needs. The sponge iron industry is a raw material industry to support the steel industry which is intended as material for shipbuilding and combat vehicles used by the Indonesian National Millitary. It is necessary to plan and design a sponge iron plant with an Industrial 4.0 model. The implementation of the Industry 4.0 model aims to optimize the operational needs of the plant, especially the sponge iron plant, which is relatively rare in Indonesia. The concept of a factory layout (cellular layout, modular layout), the concept of lean manufacturing, as well as the concepts and principles of the smart factory (Cyber-Physical Systems) are concepts that will be applied in the planning and design of the Industrial 4.0 sponge iron plant layout. In order to produce an optimal layout, a simulation model using FlexSim 2018 Software and layout optimization is used the Computerized Relative Allocation of Facilities Technique (CRAFT) algorithm with the help of CRAFT Software Integrated Microsoft Excel 2019.

The Connector Domain of Vesicular Stomatitis Virus Large Protein Interacts with the Viral Phosphoprotein

ABSTRACT Vesicular stomatitis virus (VSV) is an archetypical member of Mononegavirales, viruses with a genome of negative-sense single-stranded RNA (−ssRNA). Like other viruses of this order, VSV encodes a unique polymerase, a complex of viral L (large, the enzymatic component) protein and P (phosphoprotein, a cofactor component). The L protein has a modular layout consisting of a ring-shaped core trailed by three accessory domains and requires an N-terminal segment of P (P N-terminal disordered [PNTD]) to perform polymerase activity. To date, a binding site for P on L had not been described. In this report, we show that the connector domain of the L protein, which previously had no assigned function, binds a component of PNTD. We further show that this interaction is a positive regulator of viral RNA synthesis, and that the interfaces mediating it are conserved in other members of Mononegavirales. Finally, we show that the connector-P interaction fits well into the existing structural information of VSV L. IMPORTANCE This study represents the first functional assignment of the connector domain of a Mononegavirales L protein. Furthermore, this study localizes P polymerase cofactor activity to specific amino acids. The functional necessity of this interaction, combined with the uniqueness of L and P proteins to the order Mononegavirales, makes disruption of the P-connector site a potential target for developing antivirals against other negative-strand RNA viruses. Furthermore, the connector domain as an acceptor site for the P protein represents a new understanding of Mononegavirales L protein biology.

Effects of task and attentional selection on responses in human visual cortex

Multiple visual tasks can be performed on the same visual input, with different tasks presumably engaging different neuronal populations. The modular layout of the visual system implies that specific cortical regions carry more information about certain stimulus attributes than others. Thus it is reasonable to assume that decisions during a task will be optimal if they are based on the responses of the most informative neuronal signals, which presumably originate in regions with the sharpest tuning for the relevant stimulus feature. Previous studies have supported this position. Here we present the results of two fMRI experiments that confirm these findings and expand on earlier investigations by addressing the effects of the physical properties of an attended stimulus on task-related modulations in human visual cortex. Specifically, we ask whether performing two-alternative forced choice speed- and color-discrimination tasks (and other attentional processes) can modulate neural activity independent of visual stimulation and whether the effect of spatial attention depends on which task is being performed. The results indicate that 1) when stimulation and spatial attention are constant, responses in V4 and MT+ depend on the task being performed and are independent of the tested physical properties of the selected stimulus, 2) this task-dependent modulation might require a stimulus—task-specific preparatory mechanisms alone are not sufficient to drive responses, and 3) independent of which task is being performed, spatial attention adds a baseline shift to responses in MT+ and V4 when a stimulus is present.

Modular Visualization of Distributed Systems

Effective visualization is critical to developing, analyzing, and optimizing distributed systems. We havedeveloped OverView, a tool for online/offline distributed systems visualization, that enables modular layout mechanisms, so that different distributed system high-level programming abstractions such as actors or processes can be visualized in intuitive ways. OverView uses by default a hierarchical concentric layout that distinguishes entities from containers allowing migration patterns triggered by adaptive middleware to be visualized. In this paper, we develop a force-directed layout strategy that connects entities according to their communication patterns in order to directly exhibit the application communication topologies. In force-directed visualization, entities`' locations are encoded with different colors to illustrate load balancing. We compare these layouts using quantitative metrics including communication to entity ratio, applied on common distributed application topologies. We conclude that modular visualization is necessary to effectively visualize distributed systems since no one layout is best for all applications.

NOVEL FCS-BASED LAYOUT-FRIENDLY ACCURATE WIDE-BAND LOW-POWER CCII- REALIZATIONS

This paper presents two novel Floating Current Source (FCS)-based CMOS negative second generation current conveyor (CCII-) realizations suitable for very large scale implementation. The proposed realizations provide high voltage and current tracking accuracy, as well as large voltage and current transfer bandwidths. Simulation results show that the first proposed wide-band CCII- bandwidth is about 972 MHz. Targeting low-power dissipation, a second low-power version of the wide-band CCII- is proposed at the expense of lower bandwidth and accuracy. The proposed CCII- realizations are layout-friendly because they can be easily fabricated in a systematic modular layout fashion. In addition, a fair comparison is held between the proposed realizations and the only FCS-based CCII- realizations in the literature to show the strength of the proposed circuits. The proposed two CCII- realizations show excellent immunity to process variations and transistor mismatch. In addition, they are insensitive to the temperature variations. Finally, two common CCII- applications are presented.

Readership of Buried Ads versus Ads Placed beside Reading Matter

A study of readers of the Palatka (Fla.) Daily News finds that readers preferred modular ad layout to traditional “half-pyramid” structure by nearly 2-to-l. Further, there was no significant difference in the readers' attentiveness to ads placed either in the half-pyramid, next to editorial copy, or buried in a modular layout.
