ABSTRACT Classification of galaxy morphology is a hot issue in astronomical research. Although significant progress has been made the last decade classifying using deep learning technology, there are still some deficiencies spatial feature representation and classification accuracy. In this study, we present multiscale convolutional capsule network (MSCCN) model for morphology. First, improves layers multibranch structure to extract hidden features images. order further explore information...

Purpose The study specifically focused on ethical leadership and help seeking during innovation tested the moderating effect of happiness path from to innovation. Design/methodology/approach In this longitudinal study, 472 employees an HR outsourcing company in China participated first survey. However, only 184 completed two surveys (1 month apart). We used analysis test all hypotheses through Mplus. Findings found that leadership, help-seeking, is correlated also one’s level related...

Label placement in maps is a very challenging task that critical for the overall map quality. Most previous work focused on designing and implementing fully automatic solutions, but resulting visual aesthetic quality has not reached same level of sophistication skilled human cartographers achieve. We investigate different strategy combines strengths humans algorithms. In our proposed labeling method, first an initial computed many well-placed labels claiming to be perfect. Instead it serves...

Given a graph with edge costs and vertex profits given budget B, the Orienteering Problem asks for walk of cost at most B maximum profit. Additionally, each profit may be time window within it can collected by walk. While thus version windows are NP-hard in general, remains open on numerous special classes. Since several applications, especially planning route from A to waypoints, input restricted tree-like or path-like structures, this paper we consider orienteering these is even undirected...

Point feature labeling is a classical problem in cartography and GIS that has been extensively studied for geospatial point data. At the same time, word clouds are popular visualization tool to show most important words text data which also extended visualize (Buchin et al. PacificVis 2016). In this article, we study hybrid visualization, combines aspects of labeling. considered setting, input consist set points grouped into categories our aim place multiple disjoint axis-aligned rectangles,...

This letter analyzes the performance of a two-hop MIMO multiuser relay network with fixed gain amplify-and-forward protocol and antenna selection at transmitter receiver. A new expression for cumulative distribution function highest instantaneous end-to-end signal-to-noise ratio is derived. Based on above result, closed-form expressions outage probability bit error rate are presented. Also, diversity order system determined. Finally, computer simulations compared to analytical results,...

We consider the problem of untangling a given (non-planar) straight-line circular drawing δG an outerplanar graph G=(V,E) into planar G by shifting minimum number vertices to new position on circle. For G, it is obvious that such crossing-free always exists and we define shift∘(δG) as are required be shifted in order resolve all crossings δG. show Circular Untangling, asking whether shift∘(δG)≤K for integer K, NP-complete. n-vertex graphs, obtain tight upper bound shift∘(δG)≤n−⌊n−2⌋−2....

Map labeling is a classical problem in cartography and geographic information systems that asks to place labels for area, line, point features, with the goal select maximum number of independent (i.e., overlap-free) labels. A practically interesting case axis-parallel rectangular common size. In fully dynamic setting, at each timestep, either new label appears or an existing disappears. Then, challenge maintain cardinality subset pairwise sublinear update time. Motivated by this, we study...

The touring problem aims to find an "interesting" (round) trip of a given length. Here, what is considered interesting depends on the type desired route, e.g., user may be looking for off-road cycling or fast running route.

In this paper, a multiuser uplink amplify-and-forward (AF) relay system with multiple-antenna destination is considered where fixed-gain relaying and opportunistic scheduling are employed. Closed-form expressions for outage probability average symbol error rate (SER) in Rayleigh fading environments derived. Also, asymptotic SER presented.
