A comparison of linear and calendar travel itinerary visualizations for personal digital assistants

Various graphical travel itinerary visualization systems have in recent years been developed to allow making easier references between different events such as flights and hotel bookings on a travel itinerary, thereby addressing a problem with tabular itineraries which list travel events in a chronological order of date and time, and only allow referencing consecutive events. These graphical travel itinerary systems are based on a linear visualization of travel events. Although this linear visualization deals with some of the problems associated with tabular itineraries, it is not the only form of visualization which might be capable of addressing these issues. This paper introduces a new visualization of travel itineraries, called the calendar visualization, which relies on a more familiar concept of calendars to depict the relationships between travel events. This paper also describes an empirical study undertaken to compare the calendar and linear itinerary visualizations

From piles to tiles: designing for overview and control in case handling systems

Poor overview and control of workload in electronic case handling systems is a potential health risk factor which affects the users. Case handling systems must therefore be designed to give the users a better overview and maximum control over their workload. In an earlier study, we developed a prototype interface for managing cases, based on the piles metaphor. This paper introduces a second prototype, which is designed to incorporate the findings of an evaluation of the piles metaphor prototype. In this second prototype cases are visualized as “tiles”, reflecting the number and complexity of the cases. This paper also describes some the results of the evaluation of the tiles prototype

The significance of adopting the Islamic calendar in Islamic housing finance. Case study : Bank Muamalat Malaysia Berhad Parit Raja Branch

Malaysia is considered to be one of the most advance developed Muslim countries among Muslim countries that employ Islamic Banking system. In this context, Islamic Housing Finance has grown rapidly and becomes popular as a common solution for Muslims who desire to own home base on shariah principles. In Malaysia, banks which have Islamic Banking products employ Gregorian Calendar as the basis for their accounting system even though Surah At-Tawbah: 36-37 in Al-Quran has clearly depicted that there is a straight guidance for Muslims to use the Islamic Calendar for their mundane and spiritual lives. Factually, Gregorian Calendar is 11.5 days longer than the Islamic Calendar, thus using it will affect the calculation of loan repayment for every Muslim borrower. In previous research, discovered that Gregorian Calendar has caused the shortage of zakat payments by the Muslim customers, due to the shorter period of days calculated. This study was conducted to determine a reliable Islamic Calendar according hisab criteria (wujudul hilal) using Accurate Times. To identify the difference calculation between two calendars system and to calculate Islamic Housing Finance repayment in Islamic Calendar and Gregorian Calendar. Quantitative and Qualitative approach were employed in this research. Respondents are all customers at the Bank Muamalat Malaysia Berhad (Parit Raja) who chose Bai Bithamin Ajil (BBA) concept as their housing finance scheme. The calculation shows that total repayment in Islamic Calendar is lower than the Gregorian Calendar. Expert interview were used to identify the effect of employing Islamic Calendar in Islamic Banking system especially for Islamic Housing Finance. Finding indicates that the differences of total repayment between two calendar system reach average 1.04 per cent and most of the banks agree that Islamic Calendar can be employed as the basis of accounting system although many challenges appeared

Augmenting entry: the possibilities for utilizing geo-referenced information to improve mobile calendar applications

Today's mobile communication devices often offer extensive calendar facilities. However the use of these is often very limited through cumbersome interfaces and inappropriate designs for small devices. Prompted by previous work in mobile calendar usability, this paper discusses how augmentation of calendar entries with mobile spatial information could provide potential advantages and improve the usability of an electronic calendar

Online Circular Calendar

A calendar is a system to organize days for social, commercial or administrative purpose. Many calendar systems are available today. The calendar system helps the user in scheduling his/her events or tasks over a time period. This period may be an hour, a day, or even months. Due to increase in user’s activities, events that need to be scheduled in the calendar grow tremendously. Moreover, there are events that occur every year which require a good visualization for mental manipulation. As a result there is a difficulty in organizing these events in the current calendar system. The main idea of this project is to provide a calendar system in which users can organize the events easily, and to close the gap between the actual software and the mental model of the users. None of the current calendar systems have the ability to manipulate and plot graphs throughout the year. The data is user dependent and can be of any sort like temperature, rainfall, stock analysis etc., Apart from this; good visualization techniques can be used for the calendar system to make the events apparent to the users. By this way user can view the overall picture of the events and will have clear idea about their events. This paper describes the implementation of such a calendar system with good visualization

Testing the significance of calendar effects

This paper studies tests of calendar effects in equity returns. It is necessary to control for all possible calendar effects to avoid spurious results. The authors contribute to the calendar effects literature and its significance with a test for calendar-specific anomalies that conditions on the nuisance of possible calendar effects. Thus, their approach to test for calendar effects produces robust data-mining results. Unfortunately, attempts to control for a large number of possible calendar effects have the downside of diminishing the power of the test, making it more difficult to detect actual anomalies. The authors show that our test achieves good power properties because it exploits the correlation structure of (excess) returns specific to the calendar effect being studied. We implement the test with bootstrap methods and apply it to stock indices from Denmark, France, Germany, Hong Kong, Italy, Japan, Norway, Sweden, the United Kingdom, and the United States. Bootstrap p-values reveal that calendar effects are significant for returns in most of these equity markets, but end-of-the-year effects are predominant. It also appears that, beginning in the late 1980s, calendar effects have diminished except in small-cap stock indices.

On sharing and synchronizing groupware calendars under android platform

Indeed, the individual work of the members of the group as well as the group work as a whole need the calendar to guide their activity and to meet the deadlines, milestones, deliverables of a project, etc. Additionally the members of the group should be able to work both offline and online, which arises when members of the group use smartphones and can eventually run out of Internet connection from time to time, or simply want to develop some activities locally. In the former case, they should have access to the calendar locally, while in the later case they should access the calendar online, shared by all members of the group. In both cases they should be able to see eventually the same information, namely the local calendars of the members should be synchronized with the group calendar. For the case of smartphones under Android system, one solution could be using the Google calendar, however, that is not easily tailorable to collaborative group work. In this paper we present an analysis, design and implementation of group work calendar that meets several requirements such as 1) sharing among all of members of the group, 2) synchronization among local calendars of members and global group calendar, 3) conflict resolution through a voting system, 4) awareness of changes in the entries (tasks, members, events, etc.) of the calendar and 5) all these requirements under proper privacy, confidentiality and security mechanisms. Moreover, we extend the sharing of calendars among different groups, a situation which often arises in enterprises when different groups need to be aware of other projects' development, or, when some members participate in more than one project at the same time.Peer ReviewedPostprint (author's final draft
