Communications & Networking (COMNET)

Overview

Communications and networking research covers the range from theory to implementation of on-chip, optical, wired and wireless communication networks. Algorithm and protocol design, and system-wide policy considerations in large scale deployments of communication infrastructures are all areas of active research. Fundamental work on some of the core problems of information theory, networking, data compression, coding, and multi-user communications is emphasized. Problem formulations are guided by the needs of modern applications such as magnetic recording, digital television, voice-and-video over wireless, and gaming.

Kevin's Caesar Salad
The classic Caesar served up Kevin style, with your choice of grilled chicken or grilled shrimp. Combine both options for free on Earth Day, or half price no meat on Easter Sunday!
Kev-In Da House Salad
Back by popular demand! Kevin's scrumptious medley of mixed greens, cucumbers, tomatoes, shredded cheese and your choice of dressing is sure to start your evenings off right. If it doesn't, Kevin will DJ your next party guaranteed*!
Grilled Kevin Salad
Don't worry, Kevin's not grilling himself! A boneless, skinless chicken breast gets the grill treatment instead. Served over chopped arugula with freshly cracked pepper, shaved Parmegiano-Reggiano cheese, a squirt of lemon, and a Dijon mustard dressing. Chicken 0. Kevin 1.
French Salad a la Kevin
Kevin the Salad ChefKevin condenses a Frisée salad with goat cheese and balsamic syrup into a firm brick overnight using his patented SALBRICK® method. It is then cubed and served over Chopped Salad Niçoise. Two French salads for the price of one!
The Kevin
This is the salad that put Kevin on the map! Kevin reboots a centuries-old Mediterranean salad recipe that will have you screaming for more! Served with a complimentary side salad to quell screaming.
Kevin Once Stayed at the Waldorf Salad
You, too, will think you stayed at the historic Waldorf Astoria Hotel when you take a bite of Kevin's rendition of the infamous salad. Kevin pre-washes all ingredients with real New York City water! Choose yogurt or mayonnaise base.
Kevin-Ain't-No-Asian Salad (Summers Only)
Kevin might not be Asian... but he certainly knows how to prepare this oriental staple using only tofu and Japanese Seaweed! You'll be surprised that the tofu mandarin oranges and the tofu almond slivers taste exactly like the real thing! Domo arigato, Kevin!
Grandpa Kevin's Frog's Eye Salad
Kevin returns to his roots with this salad inspired by his grandpa, Kevin Sr. This salad mixes Acini di pepe pasta with a pineapple and mandarin orange sauce with whipped topping and miniature marshmallows. Perfect for those wanting a little dessert before their dinner.
Kev
Kevin balls up a Romaine wedge in his fist and dunks it in his famous olive oil marinade. He then punches an open bag of bacon bits and throws everything against a wall of Himalayan pink salt. Kevin then scoops what he can find with a fistful of chopped red onion and over TWO POUNDS of minced garlic. For an additional fee, Kevin will personally deliver your salad for you to eat out of his bare hands.
Simple Kevin Salad
Kevin knows not everyone craves a complex salad. Maybe they're a little intimidated by too many delicious choices? Who knows? Kevin can only guess during his sleepless nights alone on his lettuce farm. But that's neither here nor there. This salad consists of shredded iceberg lettuce in a plain plastic bowl with your choice of dressing (usually ranch) on the side.

Grill Up Some Teriyaki Chicken Kabobs
Who doesn’t love a meal on a stick?
Contributed by: Sarah W. Caron
www.sarahscucinabella.com

It’s hard to express in words how much I love foods on sticks. And kabobs like my Teriyaki Chicken, Pineapple and Pepper Kabobs are no exception.
Kabobs just scream summer to me. They are something my family has always eaten solely in the summertime. We thread on a variety of veggies, sometimes potatoes, and a meat of some sort. But after a lifetime of accepting lightly-flavored-kabobs (and liking them), I have discovered just how to make them perfectly bursting with flavor.
Teriyaki Chicken Pineapple Pepper Kabobs
The secret is in the meat. Whether you are using chicken, shrimp or beef, marinate it for a little bit. It’s amazing what just 30 minutes in marinade can do for flavoring meat. The veggies and whatever else you add don’t need to be marinated, but the meat should always be.
Marinating allows the flavor to permeate in a way that glazing just can't duplicate. (But don’t get me wrong, sometimes a nice glazed kabob is just right.)
My favorite meat for kabobs is chicken. And if you buy chicken tender strips (not the breaded kind), they are a cinch to prepare because they naturally come pieces that are 1 in. thick. Just cut into chunks, marinate it and you are ready to rock.
When making kabobs, it’s a great idea to soak your wooden skewers first so that they don’t burn. No time for that? Run them under water for 20 seconds, and that will help, too (though not as much as a good soak).
I recommend you try my Teriyaki Chicken, Pineapple and Pepper Kabobs. They’re amazing.

How has the Internet changed business in positive ways?



  
Implementation of Internet technologies in every industry has helped remove layers of transactions and shorten the 'distance' between the supplier and the consumer.

For many, this has meant major adjustments in consuming; for business, major adjustments to classic business practices. For example, a business has been able to reduce: 

  • People and staff
  • Inventory investments and stocking requirements
  • Challenges involved in dealing with multiple distribution channels


In many ways, some industries have been able to change their business models and become more profitable. Examples here are: 

  • Book publishing
  • Music packaging
  • Movie distribution
  • Banking
  • Education


HOW CAN THE BUSINESS COMPETE WITH THE INTERNET?
  
Competing as an internet business with big online names such as Amazon and large traditional businesses that now have internet operations can seem like a daunting task, and one that you will never succeed in. But never fear. Every business no matter how small has to start somewhere. In fact, if anything, competing online with big competitors is probably easier than offline.
Here are some points that needs to be considered when trying to win customers to your online business:
Offer niche products

If you can offer something different to your competitors or add value in some way then you have a better chance of people shopping on your site. Many smaller online businesses offer niche products or offer 'something different' in the way of value to attract customers.
Competitive pricing

If you can offer products or services to match the price of big established firms then there is no reason why you cannot compete. Pricing is probably the biggest factor in gaining/losing customers.
User-friendly interface

Make sure you have a shop design on your site that is extremely attractive for customers to browse. Do not pack a page with too many pictures of products. Make sure you have a very adequate product description accompanied with a nice picture. Also, do not cram the pages with too much information.
Have a search box on your site so people can enter a product they are looking for rather than having to click on too many links to find the product they re looking for.
Description of products

A thorough description of products is vital because it has to act as a way of replacing the ability to have close up look and touch of the product that would be possible if they were at an offline store.
Search engine optimization

This is a very vital ingredient for small internet businesses because it is the source of much of the free traffic that they will generate. Optimizing the site and pages will increase you page rankings and increase the flow of traffic. Remember, no matter what page they arrive on, if they like the products and value then they will stay and return in future.
Advertising

If you have an advertising budget then you could carry out Google Adword, Overture campaigns to get directed traffic. These will come to your store having clicked one of your ads so they will have read the ad and liked something about it or it could be that you have bid enough for it to appear on the top of the listings.
Payment options

You should always provide all secure payment options as different customers will use different payment methods thats conveniant to them.

What Positive And Negative Effects Has The Internet Had On Our Society As A Whole?

HOW EFFECTS THE INTERNET HAD?
There are so many effects the internet has had on our society both negative and positive. I would say the biggest positive effect is ease of information. Anyone can look up and get Information on anything whether is be health or business or legal. Alternatively, I think the biggest negative effect is ease of access to consumers by anyone wanting to make money. Consumers compulsively buy so many things on the internet that they don't need and the consumer product industries doesn't care if a home is broken because the parents or kids get access to the internet and speed money they don't have. I personally think that our society has become so fixated on the internet and spending money on things they don't need that Im sure that played apart in our current national financial crisis. Im not saying that it is the sole cause by any means but I think it certainly played into it. Anonymous
