The ongoing design evolution of a free piston compressor (FPC) is presented in this paper. The FPC is a proposed device that utilizes combustion of a hydrocarbon fuel to compress air into a high-pressure supply tank. This device is designed to extract chemically stored energy from the fuel and convert it to potential energy of compressed air, while achieving high conversion efficiency relative ...

Small object detection for 3D point cloud is a challenging problem because of two limitations: (1) The sparsity clouds significantly increases the difficulty perceiving small objects. (2) occlusion objects can easily break shape their clouds. To alleviate these problems, we design point-based network PSA-Det3D which mainly consists pillar set abstraction (PSA) and foreground compensation (FPC)....

ASL+ [SST92] is a kernel specification language with higherorder parametrisation for programs and specifications, based on a dependently typed λ-calculus. ASL+ has an institution-independent semantics, which leaves the underlying programming language and specification logic unspecified. To complete the definition, and in particular, to study the type checking problem for ASL+, the language ASL+...

1.0 Introduction Replication variance estimation for a two-stage nested sample design is usually implemented by generating replicate samples (weights) that replicate the original first-stage sample selection. Since the second-stage is nested, the second-stage variance can be reflected by associating each second-stage unit with its respective first-stage unit in each firststage replicate sample....

In the present paper, Kegelspitzen, which can be seen dcpos associated with a compatible convex structure, will be shown to be models of the order-enriched Lawvere theory of subconvex sets and later used to adequately interpret PFPC, a probabilistic version of the well-known functional programming language FPC (Fixed Point Calculus) [8], which involves recursive types.

the purpose of the present study was to compare adolescents’ academic procrastination in different family types (healthy, unhealthy, content problematic and process problematic) based on the local contextual family process and content model (fpc). the sample included 493 high school students (212 girls & 281 boys) from grades seven and eight of 8 junior high schools who were from four education...
