This document discusses flow behavior of particulate solids in bunkers and hoppers. It contains the following key points:
1. Mass flow and core flow are the two main types of particulate flow in hoppers. Mass flow avoids channeling while core flow can lead to channeling.
2. For mass flow hoppers, the hopper angle must be greater than the effective angle of internal friction. For core flow hoppers, channeling can be avoided by proper design based on parameters like wall friction angle, internal friction angle, and minimum slot width.
3. Bridging is another flow problem that can be avoided by ensuring minimum particle size, bulk density, hopper shape, and slot dimensions based on

Improving the Quality of Existing SoftwareSteven Smith
Given at DogFoodCon 2016 in Columbus, Ohio
As developers, most of our time is spent working on existing software – even if it’s just the software we wrote ourselves, yesterday. And over time, software rots. If were not diligent, our beautiful code can degrade into a worthless mess. Keeping our code in working condition is no different than changing the oil in our car “ its preventive maintenance. In this session, Steve will cover some common places to look for signs of degradation in existing applications, and describe the steps we can take to improve our code. Examples will use C# and primarily ASP.NET.
Common asp.net design patterns aspconf2012Steven Smith

UPDATE April 19, 2012: added some domain logic organization slides using Fowler's 4 basic patterns.
ABSTRACT
This project is be designed and developed to handle Frequently Asked Questions posted to various departments in a university. The University examination branch wants to maintain all the frequently asked questions in the database subject wise, to avail them to all the students whenever necessary. They will update the questions as and when required. The primary goal of the Query Handling Service is to provide an environment that is both convenient and efficient to use in retrieving and storing the information into database..
The database system must provide the safety to the information stored, despite system crashes or attempts of unauthorized access. If data are to be shared among several users, the system must avoid possible anomalous results.
Existing System
The existing system is a manual one. When the student wants to clear his query he personally contacts the concerned person in the university. The concerned person will clear his doubt.
Disadvantages:
• Difficulty in contacting the concerned person.
• Difficult to handle more students for administrator.
• Difficulty in maintaining frequently asked questions manually
Proposed System
The Query Handling Services is to replace the existing manual system with a software solution.
The University examination branch wants to maintain all the frequently asked questions in the database subject wise, to avail them to all the students. And they will update the questions as and when required in online.
The proposed system has one super user to control the data, appointing the administrators in each department. The administrator is responsible to answer all the questions posted by students.
When the student post a question in certain department the respective administrator will answer the question and a copy of the answer will be sent to the student.
Merits of This System
• Faster processing when compared to existing one.
• Maintaining frequently asked questions
• Modifications of answers can be carried out immediately
• Administrator can handle more number of students.
• Easy maintenance of administrator details.
Modules:
• Super User
• Administrator
• Student
Super User:
super user to control the data, appointing the administrators in each department,appointing the administrator to a particular department for that he register the admin,adding a new departments like computer science, chemistry, physics, maths, etc.. At the same time he can delete the departments, adding a new topic to particular department. At the same time he delete the added topics also, adding the question with answers and storing the data in database.
Administrator:
Admin can add the question with answers and it will be stored in database for students to retrieve it.
Admin will modify the answers.

Webinar is conducted by Marcin Kasz, Beacon Ambassador at Kontakt.io and Ryan Bobillo, Relationship Developer at Howler. During the webinar you will learn: - How do beacons transform retail engagement? dive into hard metrics - How to put your ideas into practice with beacon hardware? How to manage large beacon deployments? learn from others experience - Get inspired by extraordinary retail use cases! and much more...
Here are my predictions about the beacon effect:
• Beacons transform the real world into a digital channel
• It’s relatively safe since there are multiple steps required for end-users to activate beacon communications
• Consumers expect feature-rich digital experiences in the physical world
• A decrease in semiconductor costs, new mandates in marketing, and consumer adoption will fuel the adoption of beacons usage
• By 2016, beacons will be free to retailers, museums, arenas
• The profit center for beacon companies will be software, analytics, insights and consulting services
• Consumers are “warming” to the idea of trading data for enhanced experiences
• Beacons are low cost and low maintenance, as a result there will be more than 4M devices in use by end of 2018
• Beacon-delivered advertising will generate significant activity in the next 18 months
• Beacon-generated ad space will be widely available via RTB and generate $500M-plus by 2018
• Mobile phone plans will be subsidized by advertising and supported by beacon data

CW RADAR, FMCW RADAR, FMCW ALTIMETER, AND THEIR PARAMETERSveerababupersonal22
It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
