Using a data-driven approach to study and predict the shear strength of slender steel fiber reinforced concrete beams has great applicability for the design and construction process. Based on the data-driven approach, an Artificial Neural Network (ANN) model with some hyperparameters optimized by Particle Swarm Optimization (PSO) algorithm is successfully built.

Privacy-preserving frequency mining is a quite simple technique, but it is very useful in privacy-preserving machine learning and data mining. In this paper, we construct an elliptic curve analog of the ElGamal system-based protocol for privacy-preserving frequency mining in fully distributed setting.

In this tutorial I will introduce ‘learning to rank’, a machine learning technology on constructing a model for ranking objects using training data. I will first explain the problem formulation of learning to rank, and relations between learning to rank and the other learning tasks. I will then describe learning to rank methods developed in recent years, including pointwise, pairwise, and listwise approaches.

It is argued that a thesaurus, or semantic classification, may be required in the resolution of multiple meaning for machine translation and allied purposes. The problem of constructing a thesaurus is then considered; this involves a method for defining the meanings or uses of words, and a procedure for classifying them.

IN THE NEAR FUTURE an attempt to translate from a foreign language by machine will be made at the computational laboratory of Birkbeck College. It will differ from previous experiments in that the sentences or passages of French to be translated will not have been specially chosen or "doctored" in any way beforehand: on the contrary, they will be constructed by French scholars, who will be invited to do their best to fault the machine. What follows is an account of the method, or program, which makes such an experiment possible. ...

The automobile industry is a fast developing industry. From the later 18th century, when the first automobile was put on road, this industry has developed tremendously. Now there are thousands of factories all over the world manufacturing numerous type of automobile. The automobile engines are also being used in engine powered machines for agriculture, construction and manufacturing processes. Various types of small engines are also being used in lawn movers, power saws, snow removers and similar equipments.

Concept: Generators convert mechanical energy to electric energy. Motors convert electric energy to mechanical energy. The construction of motors and generators are similar. Every generator can operate as a motor and vice versa. The energy or power balance is : Generator: Mechanical power = electric power + losses Motor: Electric Power = Mechanical Power + losses.

This paper describes a compiler, which converts from Verilog to C. The output is then compiled to machine native code and tends to execute faster than native mode Verilog simulation because the compiler preserves only the synthesis semantics, not the simulation semantics, of Verilog and performs logic minimization. Busses of up to 32 or 64 bits can be modeled as C integers whereas larger busses are automatically split. We describe the motivation, method and quality of the results.

Synchronous machines come in a variety of different constructions and designs. The differences occur in the physical outlay of the rotor and in the way in which excitation flux is provided (if it is provided at all) in the machine. Regardless of the type however, all the synchronous machines have the same construction of the stator. Stator is of cylindrical crosssection, manufactured from laminated sheets of steel, and it carries a three-phase winding that is supplied with (in the motor case) or that produces (in the generator case) a system of threephase voltages....
