The work is an attempt to express the fracture toughness of fine structures consisting of a mixture of extremely thin bainite plates embedded in a matrix of austenite using a neural network method exploiting data available for martensitic and ordinary bainitic steels. The model captures reasonable trends and is able to estimate unseen exp. results on the nanostructured bainite.

This paper presents a novel design of a fingertip mechanism for detecting the slippage of the grasped object under two different types of dynamic load. This design is to be used with an underactuated triple finger artificial hand based on pulleys-tendon mechanism and the grasped object is designed in a prism shape with three DC motors with unbalance rotating mass to generate the excitation in the object, these motors are distributed symmetrically on the faces of the object. This prism shaped object is connected to a rope type pulling system to force the object to slip under quasi-static load condition. The mathematical modeling has been derived for the proposed design to generate the signal of contact force components ratio through using the conventional sensors signals with the aid of MATLAB–SIMULINK software. The experimental results are discussed in comparison with the physical aspect of slippage phenomenon and they show good agreement with the physical definition of the slippage phenomenon.

This paper represents an experimental investigation of forced convection heat transfer for three dimension laminar steady flows in three-dimensional space as rectangle-shaped box made of plastic glass its dimensions (404530) cm with two parallel heated plates inside the box. The heated plates are electrical heaters and all the walls are thermally insulated. Two vents were made at the two vertical opposite walls, one for inlet and the other for outlet of air with equal dimensions (10) cm diameter. The experiments include a study of the effect of the velocity in an enclosure as well as the effect of the exit air hole position on the forced convection at selected values of power (Pt=211.87, 316.35 and 418.08) W. This experimental work includes two cases: First case: the air enters from the middle of the enclosure and exits from the top for Reynolds number ranges (538.65 ≤Re≤1128.15) for every power (Pt). The results show that the average Nusselt number increases with the power increase for an average Nusselt number range (196.78≥(Nu) ̅ ≥95.68 ). Also, the average Nusselt number increases with the increase of Reynolds number for all power range. Second case: the air enters from the middle of the enclosure and exits from the bottom for Reynolds number ranges (545.86≤Re≤1231.68) for every power. The results show that the average Nusselt number increases with the power increase for an average Nusselt number range (228.74 ≥ Nu ≥ 107.21) . Also, the average Nusselt number increases with increase of Reynolds number for all power range, and the average Nusselt number is higher than the first case. From the experimental results of the two cases it show that the best case of the heat transfer is the second case, and the best convection heat transfer occurs at (Pt= 211.87 W).

An experimental and numerical model of a solar chimney was proposed in order to predict its performance under varying geometrical features in Iraqi environmental conditions. Steady, two dimensional, turbulent flow was developed by natural convection inside an inclined solar chimney. This flow was investigated numerically at inclination angles 15o to 60o, solar heat flux 150-750 W/m2 and chimney thickness (50, 100 and 150) mm. The experimental study was conducted using a single solar chimney installed on the roof of a single room with a volume of 12 m3. The chimney was 2 m long; 2 m wide has three gap thicknesses namely: 50, 100 and 150 mm. The performance of the solar chimney was evaluated by measuring the temperature of its glass cover, the absorbing wall and the temperature and velocity of induced air. The results of numerical model showed that; the optimum chimney inclination angle was 60o to obtain the maximum rate of ventilation. At this inclination angle, the rate of ventilation was about 20% higher than 45o. The highest rate of ventilation induced with the help of solar energy was found to be 30 air changes per hour in a room of 12 m3 volumes, at a solar radiation of 750 W/m2, inclined surface angle of 60o, aspect ratio of 13.3 and chimney length of 2 m. The maximum air velocity was 0.8 m/s for a radiation intensity of 750 W/m2 at an air gap of 50 mm thickness. No reverse air flow circulation was observed even at the largest gap of 150 mm. The induced air stream by solar chimney can be used for ventilation and cooling in a natural way (passive), without any mechanical assistance.
