P ≠ NP PROOF Millennium Prize Problem Solved using the Proof of X ± Y = B at System 1

This paper is about the proof of P ≠ NP based on the limiting factor that hinders the proof of P = NP when we consider randomness in the subset sum problem algorithm presented in this paper. Randomness in this paper is referred to an act of inputting integers to the program without pattern. The paper is not about to show case the extent in wh...

Fire Effect on Concrete Containing Red Clay (Homra ) as a Partial Replacement of Both Cement and Sand

The partial replacement of cement and sand with red clay (called also homra) in the concrete is investigated in this study, with reference to fire resistance. As a natural pozzolanic material commonly found in desert areas, homra is extensively used in brick manufacturing. As a waste material from this industry, homra is hazardous for the environme...

Influence of Fly Ash on the Properties of Self-Compacting Fiber Reinforced Concrete

Self-compacting concrete (SCC) has high flowability and high resistance to segregation and bleeding. These characteristics facilitate the mixing, casting and finishing of SCC without using compacting or vibrating machines. Adding mineral admixtures, such as fly ash (FA), and superplasticizers improves SCC properties by preventing segregation and bl...

Dynamic Structural Analysis of Great Five-axis Turning-Milling Complex CNC Machine

The computer aided engineering (CAE) with commercial software is used to analyze the free vibration frequencies, linear dynamic stress and deformation for secondary shaft system, primary shaft system and machinery bed in great five-axis turning-milling complex computer numerical control (CNC) machine. It is reasonable to use CAE software in the CNC...

Effect of Signal to Noise Ratio on Adaptive Beamforming Techniques

The capability of adaptive antenna array lies in forming higher gain in the user directions and lower gain in the interferer directions. The technique used to produce such radiation pattern by calculating the excitation weights are called the adaptive beamforming techniques. It tries to minimize the error between the desired and actual signal and m...

A Study on the Application of Spatial Directionality in Buildings

In the early 20th century, Einstein put forward the theory of time and space ---- Four-dimensional space. This paper presents a new theory of space ----- Five-dimensional space (ie, three-dimensional space, time and visible light). Five-dimensional space has the characteristics of logic, directionality and artistry. The logicality of space refers t...
