Chemical Metallization

Purpose This paper aims to present the possibility of computer-aided technology of chemical metallization for the production of electrodes and resistors based on Ni-P and Ni-Cu-P layers. Design/methodology/approach Based on the calculated parameters of the process, test structures were made on an alumina substrate using the selective metallization method. Dependences of the surface resistance on the metallization time were made. These dependencies take into account the comparison of the calculations with the performed experiment. Findings The author created a convenient and easy-to-use tool for calculating basic Ni-P and Ni-Cu-P layer parameters, namely, surface resistance and temperature coefficient of resistance (TCR) of test resistor, based on chemical metallization parameters. The values are calculated for a given level of surface resistance of Ni-P and Ni-Cu-P layer and defined required range of changes of TCR of test resistor. The calculations are possible for surface resistance values in the range of 0.4 Ohm/square ÷ 2.5 Ohm/square. As a result of the experiment, surface resistances were obtained that practically coincide with the calculations made with the use of the program created by the authors. The quality of the structures made is very good. Originality/value To the best of the authors’ knowledge, the paper presents a new, unpublished method of manufacturing electrodes (resistors) on silicon, Al2O3 and low temperature co-fired ceramic substrates based on the authors developed computer program.

Musical Creativity

In early 1950s, Iannis Xenakis became the first composer to use stochastic processes to generate pieces of music, working by hand. The first entirely computer-generated composition was Illiac.Suite.for.String.Quartett, realized by Lejaren Hiller in 1956 (Hiller, 1970, 1981). In Hiller’s approach, all kinds of musical processes were coded and implemented by computer. In the ‘80s, David Cope created a computer-aided system allowing anyone to create new compositions in the styles of past composers. The system worked even for users with no skills in programming or composition. Cope thought that computers could be a good tool for studying musical style, encoding it into programs to increase musical creativity. So he began to study the essential elements that define musical style, creating an explicit definition he could encode in a computer program.

Intersection Points

A method of calculating strain-rates and strains from an experimental flow field is developed using simple geometry with polynomials used to represent small segments of the experimental streamlines and the corresponding distance/time along streamline curves. The method is applied to an experimental flow field for plane strain extrusion obtained using printed grids (0.002 inch square), the input to the computer program being the co-ordinates of the grid intersection points and the punch velocity.

Intermittent Motion

Geneva mechanism is used as a mechanism for transforming rotary motion into intermittent motion and is able to achieve a precise movement and its lock, which makes it usable in many areas, particularly in timer devices, measurement devices, feed mechanisms, positioning mechanisms, pick-up and transport machinery, textile machinery etc. The studied literature showed that, although it has long been known, this mechanism is still interesting for contemporary researchers. The present paper proposes a method of synthesis and a computer-aided kinematic and dynamic analysis for this mechanism. Based on input data, it was developed a computer program that computes the dimensions of components of Geneva mechanism and determines velocity acceleration and displacement of Geneva wheel. The dimensional calculated data were also used to obtain 3D model of the mechanism.

Objective: This study reports the use of an interactive computer program to instruct vicarious exposure and ritual prevention for obsessive-compulsive disorder (OCD). Method: Thirteen OCD volunteers and 10 non-OCD volunteers completed three 45-minute sessions at weekly intervals. Subjects with OCD completed the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Padua Inventory (PI) and the Beck Depression Inventory (BDI) 1 week prior to and 1 week after the three computer treatment sessions. Non-OCD subjects only completed these measures at baseline, allowing confirmation that they had no significant level of OCD symptomatology. Results: In the OCD subjects, scores fell significantly on the PI and BDI, and Y-BOCS scores fell non-significantly. Engagement in vicarious exposure with ritual prevention improved from sessions 1–3. Compared to the non-OCD participants, OCD subjects did less vicarious exposure in session 1 but not sessions 2 and 3. Performance of vicarious exposure by OCD subjects in session 1 correlated with pre-post improvement in PI and BDI scores. Conclusions: The vicarious exposure program may have a role to play as an adjunct in behaviour therapy.

Manufacturing Process Selection

An interactive computer program to aid a designer in selecting candidate manufacturing process and material combinations for a part is described. The program uses a twelve-digit code to eliminate unsuitable combinations from consideration and to rank the remainder using numerical figures of merit.
