Abstract With the increasing importance of integrating different simulation tools into concurrent design environments, the demands on model complexity and interdisciplinarity have led to a growing number of interfaces between the various tools. This paper presents examples of such interfaces for the connection between multibody simulation and computer-aided control engineering tools. The interfaces introduced in this paper are classified. The application of the different interfaces is presented in two examples. Both are dealing with control of semi-active suspensions, but different methodologies are applied.

This paper deals with the development of a computerized information system for materials management and control for shipbuilding yards. It begins by critically examining the manual and semi-manual data processing methods used in medium and small-sized shipyards and highlighting their drawbacks. Based on this and with the knowledge of the ready availability of desktop computers in small/medium-sized shipyards, a computerized materials management and control system is proposed. The schema of the proposed database system is then presented by the help of block diagrams. A number of application programs have been developed to manage, control, and update the various database files under the "Network," "Purchase," "Inventory," and "Drawing" modules. The system has been tested in a simulated production environment by entering the production, planning, materials, and drawing information of two different vessels during construction. The range of information that can be obtained and the results from the proposed system are shown briefly. It is felt that a computerized information-based materials management system has a major role to play in the smooth and profitable running of a shipyard. It is very effective in a quick appraisal of complex queries relating to materials procurement, production and drawing status, and the cause of delays.

Paint flakes are often found at crime scenes as trace physical evidence that offer significance importance for forensic investigations. Matching of unknown paint flakes with known case samples may provide clues in solving crime cases. However, manual paint sample matching of case and control samples is often slow and inefficient. A paint database system for fast data retrieval is much sought after by forensic scientists. In this study, sixty building paints were examined in terms of their color appearance, solubility and Fourier–transform infrared (FTIR) analysis. Ten diagnostic functional groups were selected in IR analysis in order to discriminate between the paints analyzed. The developed database incorporated data of the paint, paint color, solubility testing and IR diagnostic peaks. These attributes were utilized for data searching, retrieval and matching with the unknown paint samples analyzed. An interactive user interface was designed based on the type of data stored in the database. The system flow follows the sequence of paint color matching, then solubility result comparison, and finally IR diagnostic group matching. The developed paint database system supports easy matching of unknown building paint fragments with that stored in the database.

The specific semantics of CAD objects are analysed concerning their nature their dynamicity and their consistency during the design process. The nature of CAD objects is concerned with their structure and relationships. The dynamicity is concerned with the evolving nature of the objects, i.e. their behavior. The consistency is concerned with their completeness and relationships with integrity constraints.A new methodology for semantic constraints management and control is defined. It relies extensively on database and expert system technologies for the implementation of new concepts, e.g. logical prototypes of objects and object equivalence class.It provides a sound and unified basis for modelling the dynamic nature of complex objects, concerning both the management of their structure and the certification of the update operations, i.e. the control of their correctness.The functionalities of CADB, a prototype expert database system that supports these features, are detailed. CADB is currently implemented in Prolog on VAX™ 11/785 and APOLLO™ workstations.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.

The majority of blood vessels in the superior cervical ganglion possess a continuous endothelium with tight junctions. These same features have been associated with the blood brain barrier of the central nervous system and peripheral nerves. These vessels may perform a barrier function between the capillary circulation and the superior cervical ganglion. The permeability of the blood vessels in the superior cervical ganglion of the rat was tested by intravenous injection of horseradish peroxidase (HRP). Three experimental groups of four animals each were given intravenous HRP (Sigma Type II) in a dosage of.08 to.15 mg/gm body weight in.5 ml of.85% saline. The animals were sacrificed at five, ten or 15 minutes following administration of the tracer. Superior cervical ganglia were quickly removed and fixed by immersion in 2.5% glutaraldehyde in Sorenson's.1M phosphate buffer, pH 7.4. Three control animals received,5ml of saline without HRP. These were sacrificed on the same time schedule. Tissues from experimental and control animals were reacted for peroxidase activity and then processed for routine transmission electron microscopy.

It is well known that the rat adrenal zona glomerulosa steroidogenic activity is controlled by the renin-angiotensin system. The ultrastructural changes in the rat zona glomerulosa cells induced by renovascular hypertension were described previously, but as far as we are aware no correlated biochemical and morphometric investigations were performed.Twenty adult male albino rats were divided into 2 experimental groups. One group was subjected to restriction of blood flow to the left kidney by the application of a silver clip about the left renal artery. The other group was sham-operated and served as a control. Renovascular hypertension developed in about 10 days: sistolic blood pressure averaged 165 ± 6. 4 mmHg, whereas it was about 110 ± 3. 8 mmHg in the control animals. The hypertensive and control rats were sacrificed 20 days after the operation. The blood was collected and plasma renin activity was determined by radioimmunological methods. The aldosterone concentration was radioimmunologically assayed both in the plasma and in the homogenate of the left capsular adrenal gland.

Scanning electron beam lithography has been used for a number of years to write submicrometer linewidth patterns in radiation sensitive films (resist films) on substrates. On semi-infinite substrates, electron backscattering severely limits the exposure latitude and control of cross-sectional profile for patterns having fundamental spatial frequencies below about 4000 Å(l),Recently, STEM'S have been used to write patterns with linewidths below 100 Å. To avoid the detrimental effects of electron backscattering however, the substrates had to be carbon foils about 100 Å thick (2,3). X-ray lithography using the very soft radiation in the range 10 - 50 Å avoids the problem of backscattering and thus permits one to replicate on semi-infinite substrates patterns with linewidths of the order of 1000 Å and less, and in addition provides means for controlling cross-sectional profiles. X-radiation in the range 4-10 Å on the other hand is appropriate for replicating patterns in the linewidth range above about 3000 Å, and thus is most appropriate for microelectronic applications (4 - 6).

Previous research has revealed that passive (involuntary inhalation) tobacco smoking during gestation can have adverse effects upon the developing fetus. These prior investigations did not concentrate on changes in fetal morphology. This study was undertaken to delineate fetal neural abnormalities at the ultrastructural level in mice pups exposed in utero to passive maternal smoking.Pregnant study animals, housed in a special chamber, were subjected to cigarette smoke daily from conception until delivery. Blood tests for determination of carbon monoxide levels were run at 15-18 days gestation. Sciatic nerve tissue from experimental and control animals were obtained following spontaneous delivery and fixed in 2.5% gluteraldehyde in 0.1M cacodylate buffer pH 7.3. The samples were post-fixed in osmium ferrocyanide (1:1 mixture of 1.5% aqueous OSO4 and 2.5% K4 Fe(CN)6). Following dehydration, the tissues were infiltrated with and embedded in Spurr. Sections were stained with uranyl acetate and lead citrate.
