We study the problem of computing a planar curve, restricted to lie between two given polygonal chains, such that the integral of the square of arc-length derivative of curvature along the curve is minimized. We introduce the minimum variation B-spline problem, which is a linearly constrained optimization problem over curves, defined by B-spline functions only. An empirical investigation indicates that this problem has one unique solution among all uniform quartic B-spline functions. Furthermore, we prove that, for any B-spline function, the convexity properties of the problem are preserved subject to a scaling and translation of the knot sequence defining the B-spline.

This paper presents a new approach to develop the strategy of Model–View–Controller architecture pattern in Business Intelligence (BI) architecture. The Business Intelligence architecture consists of the ETL tools and processes, the data warehouse, the technical infrastructure, and the user-interface tools. The major issue related to Business Intelligence architecture is to store the data from heterogeneous sources. The heterogeneous sources might lead to inconsistencies in storage and retrieval of data. Another issue related to Business Intelligence architecture is to provide multiple and synchronized views. The Business information must be presentable in various formats with ‘look and feel ’ approach. Model-View-Controller provides independent approach to the components of Business Intelligence architecture. Model provides guideline for storing the heterogeneous data in one format and implements core functionality of the system. View provides multiple and synchronized views so tha...

This thesis studies how a Model-View-Controller (MV*) framework can be integrated into a Data Visualization Pipeline. Specifically, this thesis aims to cover the challenges related in integrating an MV* framework like Backbone.js with D3.js, which is a popular JavaScript based visualization library. Additionally, it also evaluates another sub-topic regarding task runners, which are tools claiming to automate manual tasks as well as streamlining the build process.

Data Visualization has become an important aspect for many web applications. Developers need to employ sophisticated mechanisms to provide interactive visualizations. This requires separation of concerns within the visualization pipeline which is achieved with the combination of Backbone.js and D3.js. Evaluation of this methodology indicates that such a combination enables the application to be more versatile and robust while also improving performance.

In recent years, client-side web applications have become increasingly complex. A typical web application on average requires between 10-60 external open-source JavaScript libraries. Application development also requires the use of several other tools and performing manual tasks. Managing all these libraries and tools can create a bottleneck, and task-runners like Gulp aim to address these issues. This thesis implements an Automated Build Pipeline that can streamline the build process and automates all the manual tasks. The results prove significant performance and overall efficiency benefits. However, it also highlights a few serious drawbacks. Moreover, this thesis also covers some of the best practices employed by skilled front-end web developers.

Masalah yang sering ditemui dalam pengolahan data pada suatu perpustakaan adalah masih banyak perpustakaan yang belum menerapkan sistem informasi dalam pengolahan data, baik pengolahan data buku, anggota maupun sirkulasi(peminjaman dan pengembalian). Dengan sistem informasi perpustakaan berbasis web online maka akan memberikan kemudahan kepada anggota untuk mendapatkan referensi dan informasi yang diperlukan. Penelitian ini bertujuan untuk menganalisis dan merancang perangkat lunak perpustakaan berbasis web. Perangkat lunak yang akan dibangun menggunakan bahasa pemrograman PHP yang mengguanakan konsep MVC(Model, View, Controller) dengan DBMS MySQL.

Abstrak Object Oriented Programming adalah teknik penulisan kode program yang berorientasi ke objek. Object Oriented Programming sangat memungkinkan untuk diimplementasikan dengan berbagai bahasa pemrograman, karena umumnya bahasa pemrograman sudah mendukung fitur-fitur yang ada didalam teknik pemrograman ini. Penggunaan teknik ini didalam pembuatan perangkat lunak sudah banyak digunakan, dapat kita lihat dari berbagai framework seperti YII, Zend Framework dan lainnya. Adapun masalah peran dari para programmer adalah (1) Pemahaman terhadap OOPnya. (2) Tidak adanya kewajiban untuk mengembangkan perangkat lunak dengan menggunakan teknik ini. (3) kecepatan dalam pengembangan dan banyaknya jumlah kode yang harus di tuliskan menyebabkan rasa malas untuk mengembangkan. Penggunaan Bahasa Pemrograman PHP dan database MySQL merupakan pemilihan yang tepat karena akan dapat mengimplementasikan konsep client-server dan OOP.Bertitik tolak kepada hal tersebut peneliti mencoba melakukan pengembangan perangkat lunak dengan menggunakan teknik object oriented programming pada Sistem Informasi Alumni Sekolah Tinggi Manajemen Informatika dan Komputer Royal Kisaran. Dengan mengembangkan dan mendokumentasikan teknik-teknik ini maka diharapkan meningkatnya pemahaman dan jumlah pengembang yang ingin menerapkan OOP untuk masa yang akan datang.

High-intensity intermittent sprints induce changes in metabolic and mechanical parameters. However, very few data are available about electrical manifestations of muscle fatigue following such sprints. In this study, quadriceps electromyographic (EMG) responses to repeated all-out exercise bouts of short duration were assessed from maximal voluntary isometric contractions (MVC) performed before and after sprints. Twelve men performed ten 6-s maximal cycling sprints, separated by 30-s rest. The MVC were performed pre-sprints ( pre), post-sprints ( post), and 5 min post-sprints ( post5). Values of root-mean-square (RMS) and median frequency (MF) of vastus lateralis (VL) and vastus medialis (VM) were recorded during each MVC. During sprints, PPO decreased significantly in sprints 8, 9, and 10, compared to sprint 1 (- 8 %, - 10 %, and - 11 %, respectively, p < 0.05). Significant decrements were found in MVC post (- 13 %, p < 0.05) and MVC post5 (- 10.5 %, p < 0.05) compared to ...

ABSTRACT Every software program that interacts with a user requires a user interface. Model-View-Controller (MVC) is a common design pattern to integrate a user interface with the application domain logic. MVC separates the representation of the application domain (Model) from the display of the application's state (View) and user interaction control (Controller). However, studying the literature reveals that a variety of other related patterns exists, which we denote with Model-View- (MV) design patterns. This paper discusses existing MV patterns classified in three main families: Model-View-Controller (MVC), Model-View-View Model (MVVM), and Model-View-Presenter (MVP). We take a practitioners' point of view and emphasize the essentials of each family as well as the differences. The study shows that the selection of patterns should take into account the use cases and quality requirements at hand, and chosen technology. We illustrate the selection of a pattern with an example of our practice. The study results aim to bring more clarity in the variety of MV design patterns and help practitioners to make better grounded decisions when selecting patterns.

We studied the finger interactions during maximum voluntary force (MVF) production in flexion and extension in children and adults. The goal of this study was to investigate the age-related changes and flexion–extension differences of MVF and finger interaction indices, such as finger inter-dependency (force enslaving (FE): unintended finger forces produced by non-instructed fingers during force production of an instructed finger), force sharing (FS; percent contributions of individual finger forces to the total force at four-finger MVF), and force deficit (FD; force difference between single-finger MVF and the force of the same finger at four-finger MVF). Twenty-five right-handed children of 6–10 years of age and 25 adults of 20–24 years of age participated as subjects in this study (five subjects at each age). During the experiments, the subjects had their forearms secured in armrests. The subjects inserted the distal phalanges of the right hand into C-shaped aluminum thimbles affixed to small force sensors with 20° of flexion about the metacarpophalangeal (MCP) joint. The subjects were instructed to produce their maximum isometric force with a single finger or all four fingers in flexion or extension. In order to examine the effects of muscle–force relationship on MVF and other digit interaction indices, six subjects were randomly selected from the group of 25 adult subjects and asked to perform the same experimental protocol described above. However, the MCP joint was at 80° of flexion. The results from the 20° of MCP joint flexion showed that (1) MVF increased and finger inter-dependency decreased with children’s age, (2) the increasing and decreasing absolute slopes (N/year) from regression analysis were steeper in flexion than extension while the relative slopes (%/year) with respect to adults’ maximum finger forces were higher in extension than flexion, (3) the larger MVF, FE, and FD were found in flexion than in extension, (4) the finger FS was very similar in children and adults, (5) the FS pattern of individual fingers was different for flexion and extension, and (6) the differences between flexion and extension found at 20° MCP joint conditions were also valid at 80° MCP joint conditions. We conclude that (a) the finger strength and independency increase from 6 to 10 years of age, and the increasing trends are more evident in flexion than in extension as indexed by the absolute slopes, (b) the finger strength and finger independency is greater in flexion than in extension, and (c) the sharing pattern in children appears to develop before 6 years of age or it is an inherent property of the hand neuromusculoskletal system. One noteworthy observation, which requires further investigation, was that FE was slightly smaller in the 80° condition than in the 20° condition for flexion, but larger for extension for all subjects. This may be interpreted as a greater FE when flexor or extensor muscles are stretched.
