Does the Algorithm Heal a Company Organization?

Web-based systems have entered the school and business environment widely and globally. Simultaneously, instant connections such as those enabled by twitter in everyday life have bled into the workplace, calling for a relational multimedia platform with a universal interface to facilitate knowledge flows, with cross-pollination in terms of “knowing that,” “knowing how,” and “knowing why.” The use of PEGs is interwoven throughout the processes related to the introduction of relational multimedia platforms into organizations—pre-implementation, during implementation, during on-job training, and in the process of work itself—helping develop the coherence necessary for successful and sustainable business.

ELECTROMYOGRAPHY (EMG): A BIO-MEDICAL TECHNIQUE USED FOR ACQUIRING DATA DURING MASTICATION OF FOOD

The main objective of this study was to understand the technique of Electromyography. In this technique activities of muscles were governed on the basis of generated my electrical signals. Electromyography instrumentation consists of data acquisition unit, Universal interface module, Connector, adaptor and software. Various parameters like chew number, mastication time, total burst duration, total muscle activity, burst duration, inter burst duration, cycle time, muscle activity and amplitude were used for analyzing the data acquired during mastication of food at entire mastication, per chew and at three different stages (early, middle and late) of mastication.

Modeling and Dynamics Analysis of a Universal Interface for Constructing Floating Fractional Order Mem-Elements

Fractional-order systems generalize classical differential systems and have empirically shown to achieve fine-grain modeling of the temporal dynamics and frequency responses of certain real-world phenomena. Although the study of integer-order memory element (mem-element) emulators has persisted for several years, the study of fractional-order memory elements (FOMEs) has received little attention. To promote the study of the characteristics and applications of mem-element systems in fractional calculus (FC) and memory systems, in this paper, we propose a novel universal interface for constructing floating FOMEs. When the topological structure of the interface remains unchanged, the floating fractional-order memristor (FOMR), fractional-order memcapacitor (FOMC) and fractional-order meminductor (FOMI) emulators can be realized by using the impedance combinations of different passive elements, without any mem-element emulators and mutators. When compared with previously proposed FOMEs, the proposed fractional-order mem-element emulators based on a universal interface not only feature the characteristics of floating terminals and simpler circuit structures, but can also realize all three different types of FOMEs. To explore the dynamical relationships between the mem-elements and the fractional order, we mathematically derive and analyze the maximum and minimum possible values of memductance, memcapacitance and inverse meminductance which accounts for practical design considerations when building FO systems. The memory characteristics of FOMEs are analyzed by varying their orders and stimuli frequencies. The consistency of theoretical analysis, numerical calculation and simulation results validates the correctness of our proposed emulators.

Design And Validation of A Sheet Metal Clamping System For Additive Manufacturing and Post-Processing

Automated clamping for post-processing of mass-customized parts is a challenging step in the laser powder bed fusion (LPBF) process chain. In this study, a novel modular sheet metal clamping system was developed that uses disposable sheet metal profiles as a universal interface for the LPBF, robotic handling, and milling processes. Based on a fundamental investigation of hybrid additive manufacturing, the sheet metal clamping system was designed to use the same interface for the LPBF and milling processes. Subsequent an end-to-end validation was performed for the entire process chain. The concept of the sheet metal clamping system gives milling tools access to a part on five to six sides. Further, the part can be accessed from the top and bottom sides, and simplifying the removal of LPBF supports. No clamping forces are induced in the LPBF part, which is especially important for filigree structures. The sheet metal clamping system’s underlying concept could be adapted to automating the LPBF process chain for applications such as prosthetic dentistry.

Homogenization of Composites with Extended General interfaces: Comprehensive Review and Unified Modeling

Interphase regions that form in heterogeneous materials through various underlying mechanisms such as poor mechanical or chemical adherence, roughness, and coating, play a crucial role in the response of the medium. A well- established strategy to capture a finite-thickness interphase behavior is to replace it with a zero-thickness interface model characterized by its own displacement and/or traction jumps, resulting in different interface models. The contributions to date dealing with interfaces commonly assume that the interface is located in the middle of its corresponding interphase. We revisit this assumption and introduce a universal interface model, wherein a unifying approach to the homogenization of heterogeneous materials embedding interfaces between their constituents is developed. The proposed novel interface model is universal in the sense that it can recover any of the classical interface models. Next, via incorporating this universal interface model into homogenization, we develop bounds and estimates for the overall moduli of fiber-reinforced and particle-reinforced composites as functions of the interface position and properties. Furthermore, we elaborate on the computational implications of this interface model. Finally, we carry out a comprehensive numerical study to highlight the influence of interface position, stiffness ratio and interface parameters on the overall properties of composites, where an excellent agreement between the analytical and computational results is observed. The developed interface-enhanced homogenization framework also successfully captures size effects, which are immediately relevant to emerging applications of nano-composites due their pronounced interface effects at small scales.
