The paving industry within the last century has developed extensively, mainly two paving
technologies have targeted in this development, namely: flexible and rigid pavements. Although
such technologies’ development is deeply enhanced, they still have unsolved shortcomings.
Therefore, pavement researchers and engineers suggested benefiting from these two technology
advantages by gathering them in a new technology called semi-flexible paving (SFP) to overcome
the pointed shortcoming. The structural composition of SFP consists of porous asphalt, which
contains air voids (25-35) % that inject with cementitious grout materials. As a result, the SFP
surface course combines the pre-eminent qualities of bituminous pavements (flexible) and concrete
(rigid). Serving the literature disclosed that the SFP has a very high resistance to the effect of traffic
loads and weather conditions compared to conventional hot mix asphalt (HMA). Previous studies
have shown that it can be applied in places with heavy traffic, i.e. heavy and slow traffic, for
example, industrial areas, harbors, warehouses, distribution centers, road crossing, bus terminals,
parking areas with heavy traffic, cargo centers, airports pavements, etc. Therefore, under
uncontrolled high axle loads and extreme high summer and low winter ambient temperatures, SFP
represents a suitable and achievable technique.

The main purpose of the journal bearing is to support the rotating parts by providing a
sufficient layer of lubricant to separate the surfaces of the moving parts and to minimize the friction
due to rotation. The misalignment is one of the common problems in the industrial applications of
this type of bearing which has consequences on the general performance of the bearing system. The
consequences include the reduction in the bearing load carrying capacity and the effect on the levels
of the pressure distribution in additional to the asymmetrical pressure distribution along the bearing
width. This study considers extreme cases of misalignment using a 3D model of the shaft deviation
for the case of a finite length bearing. Numerical solution for Reynolds equation is considered in
this work using the finite difference method where the static and dynamic characteristics of finite
length journal bearing are investigated. The results reveal that the film thickness reduces
significantly particularly at the edges of the additional to the presence of pressure spikes at these
locations. Furthermore, the results of the dynamic coefficients have shown that the 3D
misalignment affects these coefficients significantly which may have further consequences on the
stability of the system.

Windmills require continuous observing and command to attain the required output
power when the wind velocity has fluctuated. Command a nonlinear physical windmill needs
an efficient regulator that calibrates the environment\'s fluctuations and initial conditions. As
the fluctuations in wind speed are continuous, the conventional type of control will not be
active for most cases of wind variations. An efficient control technique has been suggested to
damp the impacts of non-linearity property. The current research provides modeling,
numerical verification, and analysis of model reference fuzzy control scheme for direct drive
wind turbine coupled with a Permanent Magnet Synchronous Generator tied with the
electrical network. The machine side control is designed to capture the most considerable
energy to get better wind power production. The grid side control regulates the bus voltage
that is transformed into regulated three-phase grid voltage and frequency. The main control
objectives of Proportional Integral control and model reference fuzzy control have been
simulated and then compared. Armature profiles are also verified for different cases of
operation through simulation. This controller\'s behavior guarantees excellent dynamic
performance with wind speed variation due to the control system\'s robustness.

Food waste has a number of impacts, such as: economic, environmental and social. Recent
efforts in human computer interaction research have examined methods with the goal of
manage surplus food and food waste prevention. In addition, existing approaches have
number of limitations related to the techniques used and food waste phase focused. In
addition, to our knowledge, no approach provides an open access data for food waste (e.g.,
open API) to be used by any interested entities for data analysis.
In this paper, the effectiveness of a number of engineering approaches in the literature is
investigated and an analytical comparison is demonstrated. The second step is highlighting
the pros and cons of the proposed strategy. Finally, we propose “FoodWise”, suitable tool for
implementing the proposed strategy, by combining geo-localization, gamification, and
crowdsourcing techniques. The contribution of this study might present a new opportunity
for any interested stockholders to play a significant role in minimizing food waste
problem.

The human-like robot denotes a hopeful in the clinical, Handicapped and mechanical
prosthetics application. The finger’s control by verbally instruction is one of the significance of
such applications. Here, we introduce the suggested structure of the hand controls circuit come
from the voiced command. This structure depends on the controlling of electrical motors, for
every finger by controller. From recognition process, an Arduino have gotten a coded sign
(PWM) to give all motors signals by various\' period to the servo motor to yield the necessary
procedure which is matching to the verbally expressed words. Anywhere these codes are
identified with statistical features, which are extorted from the verbally expressed signs. At that
point, and by means of the Radial Basis Function (RBF) as a classifier, the recognition
percentage are from 90% - 99.375% have been increased with independent talker, wherever
these results are over-achieved the previous works, approximately with 2.045%. The simulation
has been made by using Matlab 2017b.
