DC Console Using DC Console Application Design Software
DC Console Using DC Console Application Design Software DC Console is easy-to-use, application design software developed specifically to work in conjunction with AML’s DC Suite. Create. Distribute. Collect. Every LDX10 handheld computer comes with DC Suite, which includes seven (7) pre-developed applications for common data collection tasks. Now LDX10 users can use DC Console to modify these applications, or create their own from scratch. AML 800.648.4452 Made in USA www.amltd.com Introduction This document briefly covers how to use DC Console and the features and settings. Be sure to read this document in its entirety before attempting to use AML’s DC Console with a DC Suite compatible device. What is the difference between an “App” and a “Suite”? “Apps” are single applications running on the device used to collect and store data. In most cases, multiple apps would be utilized to handle various operations. For example, the ‘Item_Quantity’ app is one of the most widely used apps and the most direct means to take a basic inventory count, it produces a data file showing what items are in stock, the relative quantities, and requires minimal input from the mobile worker(s). Other operations will require additional input, for example, if you also need to know the specific location for each item in inventory, the ‘Item_Lot_Quantity’ app would be a better fit. Apps can be used in a variety of ways and provide the LDX10 the flexibility to handle virtually any data collection operation. “Suite” files are simply collections of individual apps. Suite files allow you to easily manage and edit multiple apps from within a single ‘store-house’ file and provide an effortless means for device deployment. -

Cluster Generate — Generate Grouping Variables from a Cluster Analysis
Title stata.com cluster generate — Generate grouping variables from a cluster analysis Description Quick start Menu Syntax Options Remarks and examples Also see Description cluster generate creates summary or grouping variables from a hierarchical cluster analysis; the result depends on the function. A single variable may be created containing a group number based on the requested number of groups or cutting the dendrogram at a specified (dis)similarity value. A set of new variables may be created if a range of group sizes is specified. Users can add more cluster generate functions; see[ MV] cluster programming subroutines. Quick start Generate grouping variable g5 with 5 groups from the most recent cluster analysis cluster generate g5 = groups(5) As above, 4 grouping variables (g4, g5, g6, and g7) with 4, 5, 6, and 7 groups cluster generate g = groups(4/7) As above, but use the cluster analysis named myclus cluster generate g = groups(4/7), name(myclus) Generate grouping variable mygroups from the most recent cluster analysis by cutting the dendrogram at dissimilarity value 38 cluster generate mygroups = cut(38) Menu Statistics > Multivariate analysis > Cluster analysis > Postclustering > Summary variables from cluster analysis 1 2 cluster generate — Generate grouping variables from a cluster analysis Syntax Generate grouping variables for specified numbers of clusters cluster generate newvar j stub = groups(numlist) , options Generate grouping variable by cutting the dendrogram cluster generate newvar = cut(#) , name(clname) option Description name(clname) name of cluster analysis to use in producing new variables ties(error) produce error message for ties; default ties(skip) ignore requests that result in ties ties(fewer) produce results for largest number of groups smaller than your request ties(more) produce results for smallest number of groups larger than your request Options name(clname) specifies the name of the cluster analysis to use in producing the new variables. -
How the /Etc/Passwd File Relates to the Laua User
Page 1 (2) System Foundation 9.0 laua User and Group How the /etc/passwd File Relates to the laua User Scenario Most users who need access to the Lawson environment will need to have a user account set up on the Operating System where Lawson System Foundation 9.0 has been installed. Users will need resources allocated to run their jobs and space in the directory structure to store their print files. The user account on the Operating System is what allows the allocation of resources and space. In the example presented in this session, users are associated to the Unix Operating System and setup via the /etc/passwd file. The information stored on the user account in the file is used by Lawson’s Legacy Security System, laua. This scenario will present the /etc/passwd file and highlight the important parts of the user represented in the file and how it relates to user setup. Workflow Step 1 of 3: To verify that a user has an account on the Unix Operating System where the Lawson server resides, view the /etc/passwd file on the Lawson server. To do so, you must first access a command line which can be done either through LID (Lawson Insight Desktop) or through lawterminal which is command line access through the Lawson portal. This demonstration will use LID. First access your command line. Action: Type in 'cd /etc' and press the 'Enter' key. © Copyright Lawson Learning 2008 Page 2 (2) Step 2 of 3: You can use any method you choose to view the file. -

Unix Programming
P.G DEPARTMENT OF COMPUTER APPLICATIONS 18PMC532 UNIX PROGRAMMING K1 QUESTIONS WITH ANSWERS UNIT- 1 1) Define unix. Unix was originally written in assembler, but it was rewritten in 1973 in c, which was principally authored by Dennis Ritchie ( c is based on the b language developed by kenThompson. 2) Discuss the Communication. Excellent communication with users, network User can easily exchange mail,dta,pgms in the network 3) Discuss Security Login Names Passwords Access Rights File Level (R W X) File Encryption 4) Define PORTABILITY UNIX run on any type of Hardware and configuration Flexibility credits goes to Dennis Ritchie( c pgms) Ported with IBM PC to GRAY 2 5) Define OPEN SYSTEM Everything in unix is treated as file(source pgm, Floppy disk,printer, terminal etc., Modification of the system is easy because the Source code is always available 6) The file system breaks the disk in to four segements The boot block The super block The Inode table Data block 7) Command used to find out the block size on your file $cmchk BSIZE=1024 8) Define Boot Block Generally the first block number 0 is called the BOOT BLOCK. It consists of Hardware specific boot program that loads the file known as kernal of the system. 9) Define super block It describes the state of the file system ie how large it is and how many maximum Files can it accommodate This is the 2nd block and is number 1 used to control the allocation of disk blocks 10) Define inode table The third segment includes block number 2 to n of the file system is called Inode Table. -
Install and Run External Command Line Softwares
job monitor and control top: similar to windows task manager (space to refresh, q to exit) w: who is there ps: all running processes, PID, status, type ps -ef | grep yyin bg: move current process to background fg: move current process to foreground jobs: list running and suspended processes kill: kill processes kill pid (could find out using top or ps) 1 sort, cut, uniq, join, paste, sed, grep, awk, wc, diff, comm, cat All types of bioinformatics sequence analyses are essentially text processing. Unix Shell has the above commands that are very useful for processing texts and also allows the output from one command to be passed to another command as input using pipe (“|”). less cosmicRaw.txt | cut -f2,3,4,5,8,13 | awk '$5==22' | cut -f1 | sort -u | wc This makes the processing of files using Shell very convenient and very powerful: you do not need to write output to intermediate files or load all data into the memory. For example, combining different Unix commands for text processing is like passing an item through a manufacturing pipeline when you only care about the final product 2 Hands on example 1: cosmic mutation data - Go to UCSC genome browser website: http://genome.ucsc.edu/ - On the left, find the Downloads link - Click on Human - Click on Annotation database - Ctrl+f and then search “cosmic” - On “cosmic.txt.gz” right-click -> copy link address - Go to the terminal and wget the above link (middle click or Shift+Insert to paste what you copied) - Similarly, download the “cosmicRaw.txt.gz” file - Under your home, create a folder
