With smart factory investment expected to increase 20% year-on-year over the next five years and total investment expected to reach $275 billion worldwide by 2027, the use of Artificial Intelligence (A.I.) to manage operations is receiving considerable attention.  This paper takes an in depth look at how factory data is being generated, stored, processed, transferred, trained and ultimately validated using A.I.  The conclusion is that deep machine learning is more than capable of controlling devices.  Yet, research shows only 14% of smart manufactures would describe their A.I. efforts as successful.  The problems are cost and application.  Smart manufacturing is almost exclusively done by multi-billion dollar operations.  Is this money well spent?  Factories aren’t closed, linear systems. In these chaotic systems infinitesimal changes in any one of the myriad of input variables are capable of producing disproportionate changes in output values. As a result, no matter how much scrap, downtime, sales or on-time delivery data a company collects actual values will diverge exponentially from what existing A.I. algorithms are predicting.  Until more research is done predicting dynamic, nonlinear systems A.I. will not be capable of running a factory without human involvement.

This research aims 1) to study media exposure behavior of various age target groups: teenager, working age, and elderly, 2) to develop suitable media for public relations of Thai food to specific target groups, and 3) to study media satisfactory of Chinese to the integrated media for public relations of Thai food innovation to global market. The studied groups include 249 tourists both Chinese and others who travelled in Thailand and 100 Chinese tourists in Shanghai, China. The research tools are 1) integrated public relations media of Thai food innovation including website, video, mobile application, and publications, 2) satisfactory survey, and 3) questionnaire on media exposure behavior on public relations media of Thai food to global market. The survey and questionnaire were offered in Chinese and English languages. Results suggest that media exposure behavior of the tourist on Thai food information are not significantly different among nationality. There is no relationship between age and media exposure behavior. The most favorable media among tourists is online social media, followed by mobile application and website, respectively. Chinese prefers to receive information on Thai food via online social media, while the others prefer to receive the information via mobile application. Chinese would like to know about Thai food innovation, while others would like to learn about Thai food recipe. The study suggests that the suitable integrated media for public relations of Thai food to Chinese should be presented in Chinese language and published in most common social media among Chinese such as WeChat and Youku.

Leptin is a hormone secreted from adipose tissue, proved to be related to inflammatory, hemostatic, and metabolic factors, and thought to be involved in the development of hypertension. We aim to evaluate serum leptin levels and lipid profile in males with elevated blood pressure to be compared with healthy controls males of matched body mass index (BMI) and age. The present study were included 50 subject, 24 healthy controls males whose BMI (Mean±SD 27.6±4.9) as control group and 26 hypertensive males with essential hypertension whose BMI (Mean±SD 28.3±3.4), those two groups were aged and BMI matched Fasting serum leptin level, triglyceride (TG), total serum cholesterol, high density lipoprotein(HDL) and low density lipoprotein(LDL) were measured. Leptin was found to be significantly higher in the hypertensive males (group2) when compared with the control group (group1) (21.5±2.3ng/ml against 14.3±1.4 ng/ml, respectively; p0.03), while a very high significant difference in triglyceride, systolic and diastolic blood pressure (p 0.0001) and a significant difference in cholesterol was (p 0.01), LDL was (p0.01) and HDLwas (p0.05). The present study concluded that male patients with elevated blood pressure had significantly higher serum leptin level compared with healthy subjects of a same BMI. More over patients with hypertension had an unfavorable lipid profile.

Dynamic analysis can be used to find dynamic displacements, time history, and the frequency content of the load. One analysis technique for calculating the linear response of structures to dynamic loading is a modal analysis. In modal analysis, we decompose the response of the structure into several vibration modes. A mode is defined by its frequency and shape. Structural engineers call the mode with the shortest frequency (the longest period) the fundamental mode. Holzer and Stodola's approximate methods for determining the forms and periods of oscillation for frame structures are presented in the paper. An approximation method, based on approximate relative stiffnesses of the storeys and the ground floor, is analyzed and proposed. The results obtained by the proposed approximate procedure do not greatly deviate from those obtained by more accurate calculations. It is therefore emphasized that the method can be used both in practice and for checking computer-based analysis of complex systems. At the end of the paper was given a comparison of the results obtained by approximate methods and some engineering software.

A simple, rapid, and specific spectrophotometric method was developed for the determination of paracetamol  in pure form and drug formulations. The method depended on the hydrolysis of paracetamol to p-aminophenol, which, oxidized under the effect of dissolved oxygen to benzoquinoneimine. In the alkaline medium, benzoquinoneimine reacts with Methyldopa to produce a high stabile indophenol dye. The absorbance was measured at 580 nm, and the molar absorptivity was found to be 7.75 x 10-5 L/(mol cm). Paracetamol was determined in pharmaceutical products in the 10–100 μg.mL-1 concentration range with a detection limit of 1.5 μg.mL-1 PAP. The developed method can be applied to the determination of both paracetamol and p-aminophenol in the presence of each other without prior separation. The proposed method is successfully employed for the determination of paracetamol in various synthetic mixtures and pharmaceutical preparations. Our obtained results were statistically compared with those given by the similar methods and the procedures evaluated as regards to both figures of merit and ease of applicability.

Following the famous third physical Newton’s laws, “for every action there is an equal and opposite re-action”, a new approach for analysis and design of dynamic systems was introduced by [Zacher, 1997] and called «Antisystem-Approach» (ASA). According to this approach, a single isolated dynamic system does not exist alone. For every dynamic system, which transfers its inputs into outputs with an operator A in one direction, there is an equal system with the same operator A, which transfers other inputs into outputs in opposite direction. The antisystem does not have to be a physical system; it can also be a mathematical model of the original system. The most important feature of ASA is the exact balance between a system and its antisystem, which is called “energy” or “intensity”. In the group theory the system and antisystem are denote as antisymmetric. They build duality, which is common in many branches of sciences as mathematics, physics, biology etc. In the twenty years since first publication of the ASA there were developed different methods and applications, which enable to simplify the engineering, analysing the antisystem instead of original system. In the proposed paper is given the definition of ASA und are shown its features. It is described, how the ASA was used in electrical and chemical engineering, automation, informatics. Only several applications will be discussed, although ASA-solutions are common and could be used for wide range of dynamic systems.

Software can be employed to solve math problems and we have to cooperate with them not passively but in an active way. In this article, we present situations in which the software user should be careful in order to avoid the use of the straight commands of the software that may put a matrix in its echelon form or give straight its rank. Wrong results appear in Wolfram’s Mathematica software if the matrix has algebraic entries. Using the Gaussian elimination step by step method with the help of elementary matrices is a good strategy for the software user in such cases.

It is often argued that the sensitivity of atom interferometer depends on the geometry of the interfering atom paths, conventionally, atom interferometer are usually configured to be sensitive to all deformations including tensor and scalar field deformations, it is a promising and robust tool for obtaining a highly sensitive and accurate measurements of gravitational signals, as such they are potentially capable of testing a wide range of fundamental physics questions including gravitational decoherence. Therefore, motivated by the recent search to improve the sensitivity of the next generation atom interferometer, we derived a broad class of equations that obeys a specific geometric configuration for the interfering paths for a 2-level atom interferometer model, and in doing so, we further analysed various configurations for the geometric interpretation, in addition to interferometric influence phase shift and a possible decoherence factor which could lead to a systematic theoretical framework for future sensing of weak forces, due to, for example, gravitational waves and light dark matter.
