On the Window that follows, you will need to enter the security details about the network that the network administrator has given you. Now, the “Set up a Connection or Network” wizard will initialize and show different options, from these options, you will simply need to click on the third one that says “Manually connect to a wireless network” then hit the “Next” button at the bottom-right portion of the Window. Once the Network and Sharing CenterWindow opens, you will simply need to click on the link that says “Set up a new connection of network”. To do this, simply right-click on the Network Status indicator icon located on the System Tray.Īfter right-clicking the icon, there will be a menu that will appear and from here, you will need to click on the option that says “Open Network and Sharing Center” as shown on the screenshot above. ![]() To start, you will need to access the “Network and Sharing Center” Window of the Control Panel. It is impossible to connect to a hidden WiFi networkbut if you know the administrator, you can ask for the SSID/Network name and other security details of the network itself, you can still connect to it and that’s what we’ll show you in the next part of this tutorial. ![]() They are not everything yet because there are WiFi administrators who choose to hide their SSID (Service Set Identifier)to make their networks a lot more secure. The available wireless networks that are listed on the “Networks” screen whenever you click on the Network Status indicator icon on the system tray are not really the complete ones. It’s as simple as that, no pressing of keyboard combinations and other special buttons although you can also use these methods in case they are available on the laptop model that you are using. To start, you will need to again access the modern screen that shows all your network connections plus the Airplane mode switch by clicking on the “Network status” icon located on the System Tray as we have shown above.Īfter doing so, the modern “Networks” screen will appear once again and from here, all you need to do is flick the switch that is located under the “Wi-Fi” section and your machine’s wireless network adapter will instantly be switched off. However, if you only want to get the wireless network adapter turned off and just leave the Bluetooth adapter turned on then there’s an easy way to do it. When the Airplane mode switch is flicked to the “Off” position, all wireless communication adapters are turned off which includes WiFi, Bluetooth and others depending on your laptop model. You will also see the “Airplane mode” switch at the top portion of this screen which will allow you to turn off all wireless communication adapters whenever you’re travelling on an airplane. To do this, you will simply need to click on the Network status indicator icon that is located on the system tray as shown on the screenshot below.Īfter the icon is clicked, a modern style screen will slide-in from the right edge which lists all available networks that you’ve been connected to and as well as the ones that are currently available. In Windows 8.1, doing this is quite simple and the steps involved is the same as that in Windows 7but the screen that appears is totally different. One of the basic things that you need to learn when using your Windowsmachine is viewing the available Wireless networks that it detects. Viewing Available Networks in Your Windows 8.1 Computer In this tutorial, we will be answering all of these questions and give even more information that has to do in dealing with Wireless networks on your Windows 8.1 machine so be sure to read this article from top to bottom to learn some things that will surely help you get connected to the Internet even in the midst of hidden wireless networks. With all the devices and gadgets that are now capable of connecting to wireless networks and the Internet which is already starting to be offered for free in some countries, it is almost impossible to be in a certain location without ever detecting a single WiFi network broadcasting its signal.Ĭonnecting to a WiFi network has also evolved from a complicated process to an easier one and as devices that run the same operating system- from smartphones to tablets down to desktop computers, laptops and hybrids became popular in the market, the way of connecting to wireless network just got even simpler.īut what if a wireless network has been hidden intentionally by its administrator? Will you still be able to connect to it? If so, what are the steps involved. WiFi networks are everywhere and if there’s one thing that can describe our generation today then it would probably be something like “The WiFi Age”. ![]()

![]() ![]() For IKEv1, the VPN gateways decide whether to use Main Mode or Aggressive Mode for Phase 1 negotiations.The VPN configuration on each device specifies the Phase 1 identifier of the local and the remote device. Both gateway endpoints must use the same credential method, and the credentials must match.Įach device provides a Phase 1 identifier, which can be an IP address, domain name, domain information, or an X500 name. The credentials can be a certificate or a pre-shared key. The IKE version for both devices must match. The devices agree on the IKE version to use (IKEv1 or IKEv2).Phase 1 negotiations include these steps: IKE authenticates IPSec peers and negotiates IKE SAs during this phase, setting up a secure communications channel for negotiating IPSec SAs in Phase 2. The Phase 1 negotiation process depends on which version of IKE the gateway endpoints use. If the two VPN gateways do not complete Phase 2 negotiations before the Phase 1 SA expires, then they must complete Phase 1 negotiations again. This SA is valid for a specified amount of time. When Phase 1 negotiations are completed, the two devices have a Phase 1 Security Association (SA). The devices identify each other and negotiate to find a common set of Phase 1 settings to use. In Phase 1 negotiations, the two VPN gateway devices exchange credentials. The Phase 1 and Phase 2 configurations must match for the devices on either end of the tunnel. This agreement is called a Security Association. The purpose of Phase 2 negotiations is for the two peers to agree on a set of parameters that define what traffic can go through the VPN, and how to encrypt and authenticate the traffic. If Phase 1 fails, the devices cannot begin Phase 2. ![]() When Phase 1 finishes successfully, the peers quickly move on to Phase 2 negotiations. The main purpose of Phase 1 is to set up a secure encrypted channel through which the two peers can negotiate Phase 2. VPN negotiations happen in two distinct phases: Phase 1 and Phase 2. One device in the negotiation sequence is the initiator and the other device is the responder. This process is known as VPN negotiations. To build the VPN tunnel, IPSec peers exchange a series of messages about encryption and authentication, and attempt to agree on many different parameters. The devices at either end of an IPSec VPN tunnel are IPSec peers. ![]() ![]() If all the options above don't work, you can reinstall the software. Check to see if Adobe Print is there or not.

Furthermore, learning from the coaching education courses, a coach’s plan consists of a) formation (system of play), b) tactics (individual-lines-team), c) special tactics, and d) strategy. defenders with midfielders), and individual (one player) (Delgado & Mendez-Villanueva, 2018). defenders), inter-sectorial patterns (two lines between them, e.g. When coaches are building their team’s Game Model, they are building on collective patterns (team), sectorial (one line, e.g. Moreover, we need to bear in mind that having a clear Game Model reduces the players’ uncertainty when they play and gives them more time to develop their creativity (Delgado & Mendez-Villanueva, 2012). How to attack the depth – Coach Maurizio Sarri (Empoli – Seria A 2015/15)Ĭoaches should always be prepared to adapt to the current conditions that they are facing. One of his game model’s characteristics is to find the depth playing short to attract the opponent and find the space at their back (video 1). However, we can see coaches breaking the rules for instance, Maurizio Sarri (current Chelsea FC coach) has the same Game Model and philosophy working in a lower ranking team as working in a big team. How to build a Game Model (Delgado & Villanueva 2012).Įach team has a different game model according to their coach’s philosophy, the different profile of players that a squad has, any cultural specificities a club or country may have and so on. When devising your Game Model, you should consider several factors (figure 1).įigure 1. Therefore, whatever you are doing in your training (physical & tactical training) should link to what you would like to see in the game. Tactical Periodisation is a contemporary training approach in football that was recently introduced where the reference is always the GAME. What Are the Key Aspects That We Need to Know When Designing Our Training Sessions? A) Game Modelįootball or Soccer (in European “sport glossary”), is an intermittent sport with a) physical demands, with changes in the speed of movement and direction (e.g., walking, jogging, high intensity running, and sprinting), b) technical actions (dribbling, passes, shots, etc.) and c) tactical principles of play (e.g., playing style, formation, positioning, etc.) which ultimately determine the outcome of the match and the overall team performance. Thus, the coach has to do exercises to guide his team to do what it is intended to do in the game.” (Mourinho, 2006). “Training is worth it only when it lets you make your ideas and principles operational.

How do we implement this in our daily training process?Įvery football or fitness coach should always ask him/her self: WHY Furthermore, in modern football, match analysis and technology provide coaches with important information on the physical, technical and tactical demands of the game, highlighting each player’s performance (Sarmento et al 2014 Rein & Memmet 2016).Įvery action performed in the game includes a decision (tactical part), an action or motor skill (technical part) that requires a particular movement (physiological part) and is directed by volitional and emotional states (psychological part) (Delgado & Mendez-Villanueva, 2018). Monitoring training load is therefore essential (as all practitioners attest to), in managing the training “dose” to ensure the desired improvements in performance are attained whilst minimizing the incidence of load-related injuries (Akenhead & Nassis, 2016 Weston, 2018). Balancing Physical & Tactical Load in Soccer A Holistic Approach – Part 1: We Train as We PlayĪN ALL-TIME CLASSIC QUESTION How to achieve and manage the balance between physical and tactical training? Where does a fitness coach’s work end and where does the work of the football coach start? To begin with, training to enhance physical performance is an adaptive process that involves progressive manipulation of the physical load (Manzi et al, 2010), which is the sum of the fitness coach and football coach’s work. ![]() ![]() ![]() Moreover, SDHC media is the first practical solid state solution to physical archive.īy attaching the optional KA-MR100 dockable media recorder, it is possible to record Sony XDCAM EX compatible. The per-minute cost of SDHC memory is comparable to video tape. SDHC cards are economical, highly reliable, and make possible a recording system that consumes up to 20% less power than tape or HDD based systems. When the second card fills up, the camera reverts to recording to the first card slot, allowing for virtually unlimited recording lengths. The camera automatically begins recording on the second card when the first card fills up. The camera provides 2 memory card slots, for a total of up to 64GB of on-board storage–enough for more than 6 hours* of continuous HD recording. The GY-HM700 is the industry’s first shoulder supported camcorder to store files on inexpensive SDHC memory cards. Since no transfer or re-encoding takes place, first generation quality is always maintained. It is even possible to edit directly from the memory card. Post-production can begin immediately after shooting. There is no need to convert or rewrap files prior to editing. The GY-HM700 natively records the QuickTime file format used by Apple for Final Cut Pro.

If loperamide causes you drowsiness, take it when you can stay home and in bed…you probably shouldn’t be at work anyways! This enables you (and your tummy) to have a respite from diarrhea as your flu runs its course. However, it doesn’t treat the cause of it. I bet you didn’t realize that it can make you sleepy! Loperamide helps to calm down the irritation that causes you to have diarrhea. If you’ve ever had a bout of diarrhea with your flu symptoms, you’ve probably grabbed the Imodium. While it’s a fantastic way to fight a common cold or cold combined with allergies, take this medicine only when you are safely at home and ready to drop into your bed! This combination is why it relieves your cold symptoms so powerfully and lets you sleep. Bear in mind, however, that Nyquil also contains the previously mentioned ingredient dextromethorphan. Perhaps it’s best-known as an ingredient in Nyquil. In addition to being used in allergy and cold medications, it’s found in some sleep aid tablets due to its sedative effect. Purchase a second cough syrup without dextromethorphan for daytime use if it causes you to feel sleepy.ĭoxylamine is another antihistamine that makes this list. However, plan to take this medication as a nighttime formula. This means that you’ll get that fast relief and finally catch some much needed sleep. You grab Dextromethorphan because it quickly controls coughing. But, you’re sick with a cold and need the shut-eye. You are coughing all night and can’t get any rest. ![]() It is a super-effective cough suppressant. Those who fight sinus infections, coughs, or colds have probably tried Dextromethorphan. Consider a non-sedating allergy medication with a topical cream to treat the hives to stay more alert.ĭextromethorphan (Brand name: Robitussin DM, Mucinex DM –any with DM after the name!) ![]() However, it also makes many people very sleepy. The sedative effect in this medicine, in essence, shuts down the signal the brain sends that produces hives. It’s particularly used by allergy sufferers who break out into hives along with their sneezing and sniffling. Talk to your pharmacist to find a non-drowsy allergy controller for daytime use.Ĭhlorphenamine (Brand name: ChlorTimetron)Īnother allergy medication that has a sedative effect is chlorphenamine. To cut down on drowsiness, take diphenhydramine only before bedtime. It’s not only the active ingredient in Benadryl and its generic counterparts, but it’s also used in popular sleep aids such as Tylenol PM and Advil PM. If you suffer from allergies, you’re probably aware that diphenhydramine is very effective at keeping them in check. For that reason, we are focusing today on the top 5 over the counter medicines that are notorious for making you feel sleepy or fatigued. Because prescriptions are carefully flagged with warning labels, and your pharmacist will give you detailed usage instructions, you are less likely to be left unaware of these side effects with a prescription medication than one that’s OTC. This is because you are purchasing them at your local drugstore, probably without the advice of your pharmacist. Perhaps the most dangerous of these medications are over-the-counter medications. Knowing if your medication can cause fatigue or drowsiness is one way to prevent becoming a sad statistic. The CDC report goes on to cite the use of medications as one of the top 5 reasons for drowsy or fatigued driving that leads to these accidents. Moreover, over 8,000 people perish in drowsy-related wrecks each year. In fact, they report that each year, American drivers rack up 72,000 collisions 44,000 of these wrecks result in an injury. In many states, the “drunk driving” laws and been expanded to “driving while impaired.” This could mean that if you’re driving while drowsy, you could be breaking the law in your area.Īccording to a CDC report, drowsy driving is widespread. In the most dangerous of scenarios, it can even cause your involvement in a motor vehicle collision. Drowsiness from medication can also impair learning, decrease retention of information, and make you feel just sluggish overall. When you’re fatigued or drowsy, you’re more likely to be less alert and make mistakes at work or be prone to trips or falls. ![]() Whether it’s an over-the-counter flu fighter or a prescription that you have a refill on, it’s smart to know the possible side effects of every medication that you’re taking. Before you reach for the medicine cabinet, become familiar with the medications that can cause fatigue or drowsiness. ![]() ![]() ![]() it has far smaller internal energy than steam to supply energy to working fluid at venturi to increase velocity by switching PE to KEĪn interesting point. The outer diffuser tube at the tube at the downstream of the venturi throat then typically expands in order to decrease the velocity of the ejected stream, allowing the pressure to smoothly increase to the external pressure. The outer converging-diverging tube of ejector then narrows into a mixing section where the high velocity working fluid mixes with the fluid that is drawn in by the vacuum, imparting enough velocity at the venturi throat by converting the potential energy of the working fluid into kinetic energy for it to be ejected. This causes the secondary gas to move out of the vessel or equipment and enter into the suction chamber through a suction inlet. Due to the high velocity of steam through the nozzle, a low-pressure region is created in the suction chamber. During the working process, the working fluid is expanded. The nozzle converts the high-pressure steam into the high-velocity stream which is due to Bernoulli's principle. The high-pressure steam first passes through the steam chamber and enters the suction chamber through the nozzle. This increased pressure allows the exiting gases to get out of the ejector smoothly. Here the mixed gas velocity reduces as there is an expansion of gases and there is an increase of pressure. This is taken care of by the diverging section of the diffuser. However, the pressure of mixed gases falls. ![]() The vacuum is maintained since there is no fall of velocity. Steam converts its potential energy to kinetic to reach the highest velocity. The diffuser or the converging-diverging throat gives a booster dose of velocity to the mixed gases. The velocity of steam falls while the velocity of secondary gases increases. In the converging part of the outer tube steam and secondary gases from the equipment mix. The low pressure sucks the secondary gases from the vessel. While steam velocity increases its pressure falls as it expands creating a low-pressure region around the nozzle. High-pressure steam enters through the nozzle and expands at the tip of the nozzle. The steam ejector has two parts a converging nozzle and an outer converging-diverging tube. ![]() |
