Culverts : A Framework for Your Critical Stormwater AssetsCartegraph
A culvert collapsing in a neighboring jurisdiction was the only wake-up call Multnomah County needed. It was time for them to get an accurate inventory and inspection of their 1,800 culverts—and fast. Using the Oregon DOT’s Culvert Inspection and Inventory Handbook as a framework, learn how Multnomah is leveraging GIS and Cartegraph OMS workflows to keep tabs on the life cycle of their assets and ensure they are making proactive, data-driven decisions for their citizens.

Presentation of the Structural BMP Prioritization and Analysis Tool (SBPAT) to the Los Angeles MS4 Permitee's Reasonable Assurance Analysis Subcommittee of the Technical Advisory Committee (presented 9/17/2013 by K. Susilo)
Our Surveyors have a wide range of knowledge of surveying techniques and considerable experience of surveying offshore platforms and onshore installations for the oil and gas industry. Projects undertaken have ranged from the measurement of individual spools to modeling of entire platforms. Our main area of expertise is in combining laser scanning with color photography, to produce High Dynamic Range coloured three-dimensional point clouds. Using these images, designers, engineers, project managers and construction coordinators can visualize exactly what is on the installation. Project teams rely on the precision of the survey data to fabricate items that will fit when installed, without clashes.
Our laser scans can be linked into a control network to provide a three-dimensional, geometrically accurate, model of an installation. Project teams are able to utilize these models to plan larger scopes of work that require construction across decks and between modules.
Our Surveyors can use their experience to advise clients on the most appropriate type of survey and the deliverables required for each scope of work. Before each survey the Surveyors will liaise with engineers to ensure the chosen solution is practical, and provides the required level of accuracy. Experienced in the use of the commonly used software applications, the team is able to deliver data, drawings and models that suit clients’ preferences.
Services include:
•Laser scanning
•Total station surveys
•Redline markups of isometric drawings
•Clash checking
•Plant Design Management System (PDMS) compatible coloured point clouds
•TruViews (freeware that enables 3D color images to be viewed and shared over the internet)
The critical equipment used in deepwater drilling operations is subjected to harsh environmental factors such as loop currents, extreme weather, and high seastates. It is important to understand the effects these environmental variables have on subsea wellhead and conductor integrity.
Through the use of drilling riser monitoring systems (DRMS) operational insight into the real-time status of critical equipment such as the Wellhead, Conductor, BOP, and Riser can be instantly evaluated allowing for safe and efficient decision making.
A business case and ROI justification is presented in order to show that a DRMS can reduce Non-Profitable Time (NPT) and Invisible Lost Time (ILT) and is financially justified by saving as few as 1 day of rig time.

A key part of implementing Volt-VAR control and optimization is to identify the benefits that can be attributed to VVO. The major challenge is to separate the impacts of VVO (i.e. the VVO benefits) from the impacts of factors not related to VVO, such as changing weather conditions, random customer behavior and routine operational changes (planned switching). Utilities on the panel have performed VVO measurement and verification using different methods. Each presenter will describe how the method works, data requirements, strengths and weaknesses of the approach and results. The session also will summarize work by the IEEE Volt-VAR task force to develop IEEE Guideline P1885 M&V of VVO projects for electric distribution utilities.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

I am most interested in learning how PDM LLC might work with NSC
Lets get started with pre-job analysis
PDM LLC does above. Provides 3rd party vetted and fit-to-purpose MWD survey quality control services.
Lets begin with basic MSA pre-job survey management for safe well planning
This is just a graphic to indicate effect of MSA-based placement of wells in your Clients data base, Improves well planning and anti-collsion scan accuracy. 2-sigma generally, so there is still some probability of un-expected close approach.
Yellow is QC failure. Either Btotal of Dip. Is this geomagnetic activity, offset wellbore or both? Look at nearest observatory first for activity.
Initial smooth 200nT trend in check shots is suspicious. Look at sensor toolface correlation if possible for cross-axis BHA interference.
It is very important to recognize out of design values as possible interference from offset well casing.
Close coordination with PDM LLC is important for offset wellbore detection.
Just one more thing . . . speaking from experience with DD communication problems during critical operations.
Choice depends on field location
IFR2 is less common but will improve well placement, particularly high latitudes
Very briefly . . . Segue to MI-CORR as intermediate update for DD’s
MI-CORR is a software correction that is not affected by changes in Btotal or Dip.
Not as good as IFR2 which can correct for declination changes
MWD survey management is either ‘data base’ or ‘real-time’ during drilling operations
Compare magnetic reference with gravity (inclination) reference
Single shot corrections give DD information that is needed for efficient forward plans and slide corrections.
MWD services do not always provide usable survey quality information in ‘real time’
Nominal direction (simulation) is 82 degrees.
SC correction is “worst”, ‘real-time’ azimuth is good average
Raw is off due to 500nT DSI
3rd party expertise needed to properly apply short collar corrections
Note: referring back to CHF, normal day 100nT variation and improper short collar would
result in 2 deg uncertainty this situation even with “good” btotal-dip qc value
Sometimes confusion of what the “scatter” means. Here it is simplified. Very little geomagnetic activity.
Only the reference offset causes differences.
During twinning, or intercept operations, the location of a nearby wellbore is can be monitored
