Abstract:

The conventional mechanical flocculator consisting of paddles and other mechanical equipment such as a gear box, revolving foot-bridge etc. and requiring electrical energy for operation is not suitable for rural areas of developing countries. Hence four models of static flocculators which do not involve any moving parts or mechanical equipment and do not require electrical energy for operation were fabricated and tested for hydraulic properties such as dead space and short circuiting. The relative performance of the four models was tested for four turbidities and rates of flow.

Abstract:

To cope with evolving computer viruses, antivirus programs must be periodically updated. Due to the limited network bandwidth, new virus patches are typically injected into a small subset of network nodes and then forwarded to the remaining nodes. A static patching strategy consists of a fixed patch injection rate and a fixed patch forwarding rate. This paper focuses on evaluating the performance of a static patching strategy. First, we introduce a novel autonomous node-level virus-patch propagation model to characterize the effect of a static patching strategy. Second, we show that the model

Abstract:

Composite elliptic spring is a new concept as an application of fiber reinforced plastics in automotive suspensions. It functions in the same vertical deflection mode and packaging space as a steel coil spring and has the potential of saving as much as 50 percent by weight over a steel spring. The unique feature of the elliptic spring is that the fibers are utilized in tension instead of shear, thus avoiding the inherent weakness of a composite material in a coiled configuration. Several elliptic spring elements can be mounted in series to obtain the desired spring rate. In this paper, mechani

Abstract:

The long-term stability and durability of seals are critical for various instruments and types of equipment. For static sealing, an important sealing state, there are currently two representative sealing methods, namely, pre-compressing static sealing and adhesive static sealing. In this paper, the characteristics and shortcomings of these sealing methods are summarized. At present, some static sealing requirements are urgent and difficult. For example, the deterioration of the sealing performance is an important factor which limits the service life of proton exchange membrane fuel cells and r

Abstract:

Verified static and dynamic models of an operational works were used alongside Monte-Carlo conditions and non-dominated sorting genetic algorithm II (NGSAII) to optimise operational regimes. Static models were found to be more suitable for whole water treatment works optimisation modelling and offered the additional advantage of reduced computational burden. Static models were shown to predict solutions of comparable cost when applied to optimisation problems while being faster to simulate than dynamic models.

Abstract:

Performance analysis and tuning of parallel/distributed applications are very difficult tasks for non-expert programmers. It is necessary to provide tools that automatically carry out these tasks. These can be static tools that carry out the analysis on a post-mortem phase or can tune the application on the fly. Both kind of tools have their target applications. Static automatic analysis tools are suitable for stable application while dynamic tuning tools are more appropriate to applications with dynamic behaviour. In this paper, we describe KappaPi as an example of a static automatic performa

Abstract:

Pavements of airdromes, ports and container terminals, logistics terminals, industrial areas, parking lots, waste recycling areas and etc. are affected by static and impact loads. These kinds of loading differ from typical loading of roads. Due to it, pavements affected by static and impact load are design by special models according to the main distresses – permanent deformations and thermal cracking. For this purpose, there are discussed characteristics conditioning performance of pavements affected by static and impact load.

Abstract:

In this paper, the non-smooth surface technology is applied to the surface structure of the rectangular sealing ring, and a bionic sealing ring is designed. Two-dimensional axisymmetric models of rectangular and bionic sealing rings were established. Effects of pre-compression amount, fluid pressure, friction coefficient and reciprocating velocity on the static and dynamic sealing performance of two sealing rings were studied. The results show that the seal performance of the bionic sealing ring is greater than that of rectangular. The static seal performance increases with the increasing of f

Abstract:

Code completion is an editor service in IDEs that proposes code fragments for the user to insert at the caret position in their code. Code completion should be sound and complete. It should be sound, such that it only proposes fragments that do not violate the syntactic and static semantic rules of the language. It should be complete, such that it proposes all valid fragments so that code completion can be used to construct all programs. To realize soundness and completeness, code completion should be informed by the language definition. In practice, the implementation of code completion is an

Abstract:

The axle-group weigh-in-motion system has two functions: static weighing and dynamic weighing. According to the weighing model, the accuracy of dynamic weighing is affected by the static performance. This paper analyses the size of various factors affecting the static performance, such as sensor tilt installation, platform deformation, platform tilt installation, and these errors will lead to sensor swing, bearing head tilt, gravity line of action and sensor axis direction is not consistent, thus affecting the static weighing accuracy. However static calibration is the best way to reduce or ev

Abstract:

This paper describes a subassemblage seismic test program performed on six buckling-restrained braces (BRBs). Two different brace core segment lengths and two different buckling-restraining mechanisms were examined. The applied loading histories included a qualifying quasi-static cyclic test with stepwise incremental displacement amplitudes and a dynamically applied seismic loading. A test was also carried out on a conventional bracing member for comparison purposes. The concrete-filled tube specimens exhibited satisfactory performance under the quasi-static loading protocol, regardless of the
